For example, when a Volume formula is created:
Vol [ml or cm3] = 0.523598*{D1}*{D2}*{D3}
(D1, D2, and D3 indicate a measurement result.)
In this case, the measurement (D1, D2, and D3) is a distance
measurement, so the measured data is a meter [m] unit
according to the above table.
To change into a milliliter, the system multiplies each
measurement value by 100. As a result, it multiplies a formula
by 1,000,000.
The standard unit of volume is a cube meter, so the system
multiplies the result by 1,000,000.
The system multiplies the calculation result by the coefficient
and converts it. To get a correct result, when you define the
formula, you must convert the coefficient itself, such as the
coefficient of 10^.
For example, if you want to define the following formula:
efg[g] = 10^(1.5662-
0.0108*{P1}+0.0468*{P2}+0.171*{D1}+0.00034*{P1}*{P1}-
0.003685*{P2}*{D1})

P1[cm]: Perimeter
