Ken,
I could be wrong but I think it's based on volume. I've seen Tommy on TOH instruct Kevin to use a shovel 3 parts, 2 parts, 1 part.

My dad used 3 shovels gravel 2 shovels sand and one shovel of cement. His formula worked fine.

A local fellow here told me that when building a stone wall that I need to get the thermal properties of the mortar about the same as the stones and the only way to do that was to use more sand and less cement. LOTS more sand. -------------------------------------------------------------------------------------------------------------------------------------- Otherwise the mortar will separate from the stone in the first few winters.
Brick mortar does always seem very "sandy". Of course being lazy, I would just pick up a bag of premixed brick mortar and not try to mix myself!
