To convert 840 millimeters into meters we have to multiply 840 by the conversion factor in order to get the length amount from millimeters to meters. We can also form a simple proportion to calculate the result:

1 mm → 0.001 m

840 mm → L_(m)

Solve the above proportion to obtain the length L in meters:

L_(m) = 840 mm × 0.001 m

L_(m) = 0.84 m

The final result is:

840 mm → 0.84 m

We conclude that 840 millimeters is equivalent to 0.84 meters:

840 millimeters = 0.84 meters
