Dividing by 2 or 3. Having useful amounts of precision.
- FireBeyond 10y agoBy 2? Because dividing 10 or 100 by 2 is harder than 12 by 2? Three, I'll give you. Useful amounts of precision is a nothing, if you ask me. We start teaching decimals in third grade, and the only real issue with decimals is weather, for which the difference is saying "80F vs 81F", or "26.7 versus 27.2", whose utility is ... limited. For distance, the metric system has finer grained units for precision (come on, break down inches: 1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 1/2, etc... are you going to argue that is better than 25.7cm or 257mm?). I'm not really buying it, as someone who has lived in both worlds.
- SamReidHughes 10y agoYes, two. 1 foot/16 is 3/4 of an inch. 1 m/16 is 6.25 cm. You can say 1.5 cups instead of 375 mL.
