1 square foot = 144 square inches, so 100 square ft = 14400 sq inches. Multiply be 3 = 43200 cubic inches. I believe gravel is normally sold by the cubic yard. 1 cubic yard = (36 in)3 = 46656 cubic inches. So 43200/46656 = 0.926 cubic yards
1 square km of gravel

Depends on depth of gravel you plan to put down. For each 1 inch depth: Estimate gravel having a density of 2.7. 150 x 1/12 x 62.4 x 2.7 = 2106 pounds (slightly more than 1 ton) so if you want 3 inches of gravel you need about 3 tons of gravel
To cover 300 square feet 4 inches thick, you would need approximately 3 cubic yards of gravel.
