Unit Conversions
There are many times when we need to convert units between imperial and metric
measurements. Sometimes we want to convert feet to metres or pounds to kilograms.
In baking, you may need to convert between ounces and millilitres.
To convert units, we multiply our measurement by a unit conversion factor. The
conversion factor is the unit we want, divided by the unit we have.
Example:
Convert 1.5 m to cm.
Convert 1.25 km to m.
Convert 1.5 hours to seconds.
Convert 240 seconds to minutes.
Some basic conversion factors:
1 inch = 2.54 cm
