Velocity calculation in US system from acceleration

[yosimba2000]

I've been working exclusively in SI units up until now, so using the US System trips me up.

Given force in pounds-force, I divide it by mass (units are pound-mass) to get acceleration. I take the integral of acceleration to get velocity, which, according to the US Units, are in mph. Am I reading this correctly?

If you divide pounds force by pounds mass to get acceleration you will get a result in g's. One g is approximately 32 feet/sec². For example, 3 pounds force applied to 2 pounds mass will produce an acceleration of 1.5 g's = 48 feet/sec².

You can integrate acceleration in feet/sec² over time to get a result in feet per second. Then the conversion from feet per second to miles per hour involves knowing that there are 5280 feet in a mile and 3600 seconds in an hour.
