If necessary, you can define the units that you want to use in the final results of your calculations. See the following instructions.
Example
With the format and precision settings shown, the following equations
a = 150 mm; b = 60 cm; c = 2.5m
a * b = ? F0 cm 2
a * b * c = ? F3 m 3
calculate to give
a = 150 mm; b = 60 cm; c = 2.5m
a * b = 900 cm 2
a * b * c = 0.225m 3
