What can you use to evaluate expressions with units of measure and to check for the correct units?
Treat the units as unknowns in algebra and manipulate them using the laws of indices.
eg a volume of cm³ of a substance spread over an area of cm² (say 5 cm³ spread over an area of 10 cm²) gives an answer in cm³ ÷ cm² = cm^(3-2) = cm^1 = cm (5 cm³ ÷ 10 cm² = 0.5 cm of depth).
eg density is mass over volume, thus the units of density can be kg/m³ (where mass is in kg and volume is in m³), g/cm³ (where mass is in g and volume is in cm³), etc.
eg speed = distance/time → distance = speed × time; if speed is mph (miles/hour) and time is in hours then distance = speed × time = miles/hour × hour = (miles×hour)/hour = miles {as the hours cancel}.
