I don't remember what granddad was measuring back then. I was pretty young. I do know he was talking about field work.
In college one of my physics professors had us convert different units of speed to furlongs per fortnight. My 44 Special with a 429421 and 17 grains of 2400 is going roughly 1,451,520,000 fpf (furlongs per fortnight). Makes the old 44 Special sound a little more special.
