Conversion Formula

By using the online converter calculator on this page, you can calculate how many femtometers are in 'X' kilometers (X is the number of kilometers you want to convert to femtometers). In order to convert a value from kilometers to femtometers (from km to fm) simply type the number of kilometers to be converted to femtometers and then click on the 'convert' button. The formula used for converting a specific value from kilometers to femtometers is:

X kilometers * cf = Y femtometers

where
X = the specific value to be converted (in kilometers)
cf = the conversion factor from kilometers to femtometers
Y = the result (in femtometers)

Example
Let's suppose that you have a value of length of 556 kilometers and want to express it in femtometers.
556 km = (556 × 1.0E+18) fm
556 km = 5.56E+20 fm

Conversion factor

1 kilometer is equal to 1.0E+18 femtometer
(1 km = 1.0E+18 fm )
