If you can't multiple 231 by 5280 what are you going to do when you measure a length of 23.1 cm and need to multiple it by the height of 52.80 cm? > Are you serious when you say you can't easily multiply or divide by 1000? You have missed the point. Force is a mass * distance / time. So, if I have a 1 g weight I want to move 1 meter in 1 second then it takes 1 Newton of force. Except it doesn't because Force is actually kilo-mass * distance / time. If I need to look up (or memorize) stuff like this then the entire advantage of metric goes away because I can just memorize the imperial way as well. It just comes down to what you're familiar with. There's certainly a benefit to everybody using Metric in the same reasoning as there's a benefit to everybody using Mandarin. |

Hmmm... no?
With metric, once you know what a "meter" is, you have the distances. <milli>meter, <centi>meter, <deci>meter, ... It's one unit: the meter. And fractions of it that require trivial conversions.
With imperial, you have multiple units of distance: inches, feet, yards, football fields, miles.
The benefit of metric is that you have to memorise fewer units, period. Your example is a formula in physics. There you have to memorise F = m * a AND in which units those are (bonus if they are consistent between the formulas, of course). That's strictly equivalent between imperial and metric there.

Of course, if you're familiar with imperial and not metric, then you're better off with imperial!

That's an interesting example: Mandarin is known for being a lot harder than English. Obviously, if you grew up with Mandarin and no English, you will be more comfortable with Mandarin. But people speaking Mandarin don't insist on saying that Mandarin is not harder than English, in my experience :-).
