Rebar Diameter

The Rebar Diameter function returns the diameter of the cross-section of a piece of rebar based on its size (2,3,4,5,6,7,8,9,10,11,14,18).

INSTRUCTIONS: Choose the following:

• (rS) The size of rebar  which is used to compute the diameter for lapping considerations.
• (lF)  The lapping factor is the multiple of the diameter of the rebar to specify the lapping distance.  40 (default) and 60 are common.

Rebar Diameter (rD): The calculator returns the rebar diameter in millimetres (mm).   However, this can be automatically converted into compatible units via the pull-down menu.
