Dimensions for this project are both metric and imperial. All measurements are given in millimeters first, followed by feet and/or inches in brackets ( ).
The metric sizes are not an exact match to the equivalent imperial sizes.
A project built using the metric measurements will be approximately 1.6% smaller than the same project built using the imperial (ft and in) measurements. The imperial measurements are more suited to North America. The metric measurements are more suited to Australasia.
