What is the cubic measurement for 100 liters?

A litre is 10cm x 10cm x 10cm so it's 0.001 cubic metres. That means 100L will be 0.1 cubic metres. That's the same as 6102 cubic inches or 3.53 cubic feet.

Another way to look at this is: 100L = 100*1000mL. 1mL = 1cc (cubic centimeter). Thus, 100L = 100*1000cc = 100 cubic decimeter = 0.1 cubic meter. 1in = 2.54cm. 1 cubic inch = 2.54^3 cc. So 100L = 10^5 / 2.54^3 cubic inches = 6102.37 cubic in. 1 cubic feet = 12^3 cubic inch. Therefore, 100L = 6102.37/12^3 cubic feet = 3.53147 cubic ft.
