# What is unit conversion?

Apr 2, 2014

Unit conversion is when you convert a value that is measured in one set of units to another equivalent value in another set of units.

For example, the volume of a 12 oz drink can be converted to mL (knowing that 1 oz = 29.57 mL) as follows:

12 oz; 29.57 mL/oz = 355 mL

A somewhat more complex example is to convert the speed of a car going 55 mph to metric units (m/s):

$55 \frac{m i}{h r}$ * $\frac{1609.3 m}{m i}$ * $\frac{1 h r}{3600 s} = 24.5 \frac{m}{s}$
