What is an ounce?
One sixteenth of a pound. Not to be confused with the fluid ounce, which measures volume.
What is a slug?
The mass that one pound-force accelerates at one foot per second squared — 32.174 pounds. It exists so that F = ma works in US customary units without a conversion constant, and it is why American engineering statics is not simply pounds.
How many slugs are in an ounce?
One ounce is 0.0019425594 slugs. Going the other way, one slug is 514.78478 ounces. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
