    The one thing that bothers me about the metric system is how much of it is never actually used. No one says “1 megameter”, for example. They say “1,000 kilometers”. When you think about it, most metric prefixes are never used with most metric units.

        We use decimetres in chemistry a fair bit. 1 mole of any gas will occupy 24 dm³ at rtp

        “deci” is very popular. Just not in the “correct” form “decimeter”.

        In Spanish it’s normal to say “8 décimas”, which means 8 tenths. It is context dependent though. For example if speaking in a context where millimeters are used, it will be 8 tenths of a milimiter. That is, 0,8mm.

        But yeah, it is very uncommon to use deci and deca. Because they’re just not very useful. We are used to 2 digit numbers, or numbers with 2 decimal places. So 87m is not harder to use than 8,7dam.

        It’s probably also the reason there is no prefix between kilo and mega, or milli and micro. (They are x1000 increments instead of x10).

        For the same reason, when in a context of millimeters, it’s preferred to say “87mm” instead of “8,7cm”.

      I’ve thought that was weird too. Decimeter’s seems like a good unit for measuring a person’s height, for instance.

      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

        I have no idea what you’re talking about… humans are around 1-2m tall, weigh about 40-80kg, have a body temperature of about 37 C, and need to drink a couple litres of water per day. How are these units not the proper order of magnitude for measuring things “on a human scale”?

        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.
