Imperial vs Metric

Imperial: Imperial refers to a unit of measurements in inch increments - 3/32", 1/8", 5/32" etc. Most of our mandrills come in these measurements.

 

Metric: Metric refers to a unit of measurement in decimal increments .1, .25, 2.8 etc. Usually this is in millimeters or mm. This is the defacto standard in most of the world.

Our ring stats will show both as often as possible. Sometimes there just is not an imperial equivalent.
