Document Summary

Conversions can be hard, metrics makes it easier & maintains the most precision and accuracy. Traditional development of units in different parts of the world. However, scientific calculations require si units -> mainly metric system. M k h da d c m n p.

Common metric units are: liter and milliliter, 1 l = 1 dm3, 1ml = 1 cm3. If temperature increases and volume increases, then density drops. In fermentation, we know it worked if the density drops!
