Changing unit

See original GitHub issue

Issue Description

I made a new json which includes

"cm": {
    "Dimension": [0,1,0,0,0,0,0],
    "Value": 0.01},
"mm": {
    "Dimension": [0,1,0,0,0,0,0],
    "Value": 0.001},

now i have a calculation of m * cm * mm and it’s result is m³. when i leave out the m i get a result of mm².

On what basis is the resulting unit calculated.

And how can i change it? (i want cm in both lines)

Hi @eagle-tex,

Ah, yes this part is less obvious. For specifying no prefix, as follows:

L = 3347.526*m
a = L.prefix('unity')

I need to update the documentation, badly. Ideally with a proper readthedocs site. Coming soon. Will update the Github page in the mean time.

Hi @DiegoTheWolf and @eagle-tex,

There is a method called .prefix() that accepts a string prefix to be “forced” upon the unit so that it always displays that way. It works like this:

a = 4 * m
b = 200 *mm
c = (a+b).prefix('c')
c

420.000 cm

The same would work as follows:

F2 = 1508*kN
F2

1.508 MN

F2.prefix('k')

1508 kN
