    Calling the boiling point of water simply "warm" is a bit sus.

      Tbf as someone who grew up with the imperial system due to being raised by a British boomer its fairly easy if you're familiar with it, I still often cook in imperial due to a load of old cook books I have.

      Having said that anyone who wants the imperial system in the modern day is a absolute idiot, metric is objectively superior.

      The biggest issue with imperial recipes is the constant use of measures by volume. If everything was in weight ounces it would be alright, but a lot of recipes insist on measuring solids by volume, like a cup of flour, a teaspoon of sugar etc, making them a lot harder to replicate consistently. My flour could be denser, my sugar could be finer, if things were measure by the actual mass such things would not matter but instead I have to fill a cup and pray to the gods that my cup of Ecuadorian flour has the same density as the one on the recipe (it almost never is)

        It's a fraction. So like if you had one apple to split between four people then we would all get one quarter of a whole apple.

        1 apple per 4 people = 1 per 4 = 1/4 = 0.25

        I don't know that I would say that fractions are more or less precise than decimal.

        Precision has nothing to do with the unit system. Or notation of fractions.

        0,001m is as precise as 1mm

        1/1000m is as precise as 1mm

        In SI you don't even have prefixes, you use scientific notation with base units. You don't say neither 1mm nor 0,001m. You say 1x10^-3^. Which is exactly the same as the other magnitudes of this comment.

        If you want precision in imperial, you could as easily say 0,00000000001 inch. It would be as precise as 0,000000000255 mm, or whatever the conversion is.

          F and C are both made up points, not absolute values. C is great, if what you care about is what water is doing. F is great, if you care about how something feels to a human (not saying you can't memorize new numbers, but 0 and 100 being dangerous is simple).

          If you want an actual "best" temperature scale, use Kelvin. 0 is no energy. It actually has a fundamental base. If you argue that temperatures that are useful to humans are too hard to memorize, then you're making the argument against C too (or F when dealing with water).

          F has nothing to do with how a human feels. 0 f was literally just a very cold day that happened once. You're just used to it, the same way people who use c are used to it and feel it very intuitively. A scale that actually was human would probably be logarithmic since we dont feel temperature linearly, and the 0 would be at 20c ~68 f since that is the temperature that's most comfortable for people, with positive numbers being hot temperatures and negative numbers being cold

            1/14. Easy

            If programs can handle February having 28 days, sometimes 29. It can handle 14 having 1 day, sometimes 2.

              What I'll defend, however, is fractional measurements when precision matters.

              With decimal measurements, precision can't be nearly as granular. If your measurement is precise to one 1/8 of a unit, how do you represent that in decimal? 0.625 implies your measurement is precise to the nearest thousandth, but rounding it to 1 also isn't precise. 5/8, however, tells you the measurement AND the precision.

              With fractional measurements, you can specify precision by changing the denominator to any number, whereas decimal is essentially fractional measurements, but with fixed denominator at powers of 10. For instance, a measurements of a half-unit with levels of precision between 0.1 and 0.10, fractional can be 6/12, 7/14, 8/16, 9/18, 10/20, 24/48, etc. Decimal can't specify that precision without essentially writing a sentance.

              What's simpler to record? "24/48" or "0.5 +- 0.208333...."

              That is not a flaw of decimals. It is a flaw of you not knowing how precision is encoded in decimals.

              0,7583 means 0,7583 ± 0,00005.

              0,758300 means 0,75833 ± 0,0000005.

              0,76 means 0,76 ± 0,005.

              That is why when in a store an item costs 7,5€, we don't say 7,5€. We say 7,50€. Because it is precise to a hundredth of a €, not a tenth of a €.

                But that 5/32 screw has its precision built into the measurement. Sig figs and error ranges aren't required for fractional, because both are built into the denominator.

                If your 5/32 measurement is super precise you can record it as 160/1024ths, because the denominator has "+/- 1/2048" built into the measurement.

                As I said in another (larger) comment, you just don't know how precision is encoded in decimals, which doesn't mean that it isn't. In fact, precision is encoded in decimals, just like with fractions.

                0,7 is 0,7 ± 0,05
                0,7000 is 0,7 ± 0,00005

                  But what if your precision is greater than 1/100 but not 10 times as precise?

                  If you have 0,7 that is more precise than 0,7 and less precise than 0,7. You can just say 0,7 ± 0,02.

                      I believe that's in reference to a clip of a streamer saying that repeatedly. It's not supposed to make sense I think.

                            Fahrenheit is better at describing weather in reference to human interaction with temperature Celsius is better for everything else.

                            But that's the same for everything imperial. It's always better when it comes to actual human elements. How big is that stick? How many things in that piece of bread? How much weight is that rock? I need to move.

                            While metric is basically better anytime you have tooling you need to be extremely exact. You need to know something that is less human and more mathematical or abstract.

                            Well each system can do the thing. They're not great at it quickly falls apart. That's a big reason why people tend to say imperial sucks. Most people no longer actually interact with the natural world anymore. Everything is computers, exact measurements, quantifiable numbers from shops. The only thing left that most people deal with on a day-to-day basis is the weather and why Fahrenheit may be better than Celsius. It's only vaguely better since weather is already such an imprecise thing that really doesn't matter.

                            Well yes the granularity of Fahrenheit is far more useful. If you actually want to be like specific about things Celsius when it comes to weather it's close enough f****** does the job

                            I mean, you can always use different units in different contexts. We use F for the weather but C for the kettle, personally! (C for the oven would probably also be better, but all the recipes are in F.)

                                It's because metric sucks at anything on a human scale and most people deal with things on a human scale. Imperial was developed over hundreds of years to be extremely narrow and scope in a specific two things at a human scale.

                                It's a big reason why imperial makes far more sense. If you actually need to talk about anything on a human scale, everything no matter how nonsensical makes sense the moment, it's explained because it's all extremely intuitive.

                                While metric is basically a tiny fraction of a technically Superior system that basically makes no f****** sense in 99% of cases for a day-to-day life.

                                Try metric is the measurement of science, engineering and other fields of study because they actually do with things outside of day-to-day human scope

                                Could you give an example of a situation where metric makes less sense than imperial? I will then explain to you that it only appears to you like that, because those are the units you've lived your whole life using. Without that baggage, the adaptability and easy conversions make SI-units objectively superior in every situation.

                                      It's the size of a thumb. The Dutch translation is "duim". These smaller units use tangible things to measure. A foot and a thumb is always on you.

                                        Please also lets use the International fixed calendar where every month has exactly 28 days/4 weeks and the year has 13 months.
                                        Every 1st of the month is a sunday, every 2nd is a monday and so on, so you will always know which day it is by the number.

                                        The leftover day is a dedicated new years day.

                                        Would be nice to realign September, October, November, and December as the 7th, 8th, 9th and 10th months respectively

                                          It's because metric sucks at anything on a human scale and most people deal with things on a human scale. Imperial was developed over hundreds of years to be extremely narrow and scope in a specific two things at a human scale.

                                          It's a big reason why imperial makes far more sense. If you actually need to talk about anything on a human scale, everything no matter how nonsensical makes sense the moment, it's explained because it's all extremely intuitive.

                                          While metric is basically a tiny fraction of a technically Superior system that basically makes no f****** sense in 99% of cases for a day-to-day life.

                                          Try metric is the measurement of science, engineering and other fields of study because they actually do with things outside of day-to-day human scope

                                          As the saying goes, use the right tool for the right job and only a dumb f*** uses the wrong tool for the wrong job
