If using a Weston master why not just transfer the reading to the exposure calculator?
It is the reciprocal, and you want the square root of the arithmetic film speed. And right Weston meters indicate candela per square foot. Shutters mostly leave off the 1/ . If there is time the exposure calculator is useful.
But the exposure formula is easy to use in a pinch:
Set the f/stop at the square root of film speed and set the shutter to whatever the meter needle points at.
