Those prefixes are bad because they break the 10^(3n) pattern. centi and hecto are also bad for the same reason. Most calculators have an "engineering" mode which only uses the good prefixes, because it's easier to think about prefixes when the ratios between them are consistent.
- pmontra 5y agoCentimeters are pretty common. Rulers are marked with cm and mm. We use mostly m and cm inside houses. A door width? 90 cm. A door height 2 meters and 10. And don't forget cubic centimeters (or cc) for engines. Anything from 2000 cc down to 50 cc is very common east of the Atlantic Ocean.
