Units of Length
------Fundamental Units------
Assumption: 1 Gaussian Year=31558196.01312 seconds, exactly
1 inch = .0254 meter, exactly (aka 1 International Inch)
1 meter = distance light travels in vacuum during 1/299792458 second
Standardized astronomical unit = 149597870691 meters
Standardized light year = distance light travels in vacuum during one Gaussian year
N.B.: Shading denotes defining or exact values.
