Metric constants conversion

CIMtools.metric_constants subpackage includes values of masses, volumes, etc for converting to SI values.

Usage is very simple:

from CIMtools.metric_constants import *

# convert pounds into kilograms
2 * lb

# reverse convert SI into pounds
2 / lb

# temperature conversion
25 * C  # now T in Kelvin
298 / F  # Kelvin (SI) into Fahrenheit

According to order of math operation, power has higher priority. For prevent errors use ():

2 * C ** 2  # wrong
(2 * C)  ** 2  # first convert, after square
2 * C * 3  # right
