Why Do We Convert Units?

Different situations call for different units. A doctor uses kilograms. A baker uses cups and teaspoons. A scientist uses meters. Being able to convert between units is one of the most practical math skills you'll ever learn!

The Formula

Almost every conversion is just multiplication or division by a conversion factor. For example: 1 foot = 12 inches, so 3 feet = 3 × 12 = 36 inches.
