In everyday life, we often encounter situations that require us to be able to convert units of length, mass and time. It’s not only conversion done within the same measurement type but it’s also converting US customary units or British Imperial Units into meter base unit. For example when buying ceiling projection screen 84 inches frame someone may look for centimeters conversion to check corresponding value in symbol cm. For 84 inches frame we will have length and height equal 185 cm x 105 cm.

British Imperial Units – how many cm are in 84 inches?
If we want to provide an inch value in centimeters, we need to use cm converter. Unit converter can be easily found in internet. One inch is an approximately equivalent of 2.54 cm. Simple multiplication will allow us to find out how many centimeters are in 84 inches.

Decimal fractional values – conversion factor for decimal system
By converting a larger unit to a smaller one, we multiply by 10, 100, 1000, 1,000,000, respectively. By converting a ton into kilograms we multiply by 1000, we multiply kilograms into decagrams by 100. The same formula is applied to centimeter, meter and kilometr units. Decimal fraction logic cannot be applied for US customary units which means that using that logic we cannot calculate (convert) how many inches are in 1 foot.
