Conversion Formula

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

X joules * cf = Y millijoules

X = the specific value to be converted (in joules)
cf = the conversion factor from joules to millijoules
Y = the result (in millijoules)

Let's suppose that you have a value of energy of 251 joules and want to express it in millijoules.
251 J = (251 × 1000) mJ
251 J = 251000 mJ

Conversion factor

1 joule is equal to 1000 millijoule
(1 J = 1000 mJ )
