Cubic feet to cubic yards
Divide cubic feet by 27 to get cubic yards. 100 cubic feet is 3.70 cubic yards.
Why 27
A yard is 3 ft, so a cubic yard is 3 ft × 3 ft × 3 ft = 27 cubic feet. To go from cubic feet to cubic yards divide by 27; to go back, multiply by 27. One cubic foot is 0.037 cubic yards.

Some of these numbers show up often. A yard of concrete is 45 bags of 80 lb mix (each 0.6 cu ft), a yard of mulch is 13½ bags of 2 cu ft, and a yard of bagged gravel or sand is 54 bags of 0.5 cu ft. Half a yard of gravel weighs about 1,350 lb, so before loading a pickup, check the material's weight on the cubic yards to tons page against your truck's payload.
