Using units of measurement

Sometimes, we may have data using one unit of measurement but want to draw the plot using a different unit of measurement, or sometimes we may want to use different units of measurement on the x and y axis, say centimeters on the x axis and inches on the y axis. The same is true for degrees and radians when we are plotting angles. Matplotlib does not have these functions built in, but there is an extension utility, basic_units.py, available on GitHub, which enables these different units of measurement. This Python module currently supports only centimeters/inches and radians/degrees. For other units of measurement, such as kg/lb, km/miles, and so on, we will have to update this utility module.
