Inch to Meter Ratio

It is best to leave this set to the SI Unit. The other ratios are:

Unit Radius Scale Factor

The internal model is always of a unit radius but all output dimensions are scaled by the Unit Radius Scale Factor. If you elect to construct a dome with a radius of 10 feet, set the Unit Radius Scale Factor to 10, and select ‘Feet’ as the working unit. Alternatively, if you elect to construct a dome with a radius of 12 meters, set the Unit Radius Scale Factor to 12 and select ‘Meters’ as the working unit. You may optionally convert the working unit to another type.

Some of the units on offer are rather exotic: Geodesica makes no assumptions about working in purely metric or imperial units. However, you will probably not wish to work in Megalithic Miles unless you are constructing a geodesic alien moon disguised with regolith for place in orbit around a far flung planet of special interest.

The working and converted units are printed in the Log when perfoming measurements. For example:
