I assume it is permitted, though the final answer is required in feet. That problem I'd probably do in feet, but if the problem involved acres, gallons, and feet, or if the solution required the density of water, the speed of light, the acceleration of gravity, or any other constant that's defined or simpler in metric, I'd work the problem in metric.
