A cubic feet calculator for a box or a room. Mixed units are fine. The same volume is shown in cubic inches, cubic yards, cubic meters (CBM), and liters.
Yards from an area and a depth: cubic yard calculator. Flat area with no height: square footage calculator.
Box or room volume
Each side has its own unit. The box is a rectangular prism. Quantity multiplies that one box. Doors, windows, and waste are not subtracted. Cubic yards for a pad, with a depth and a shape menu, stay on the cubic yard page.

How the cubic feet are calculated
Convert each side to feet, then multiply length × width × height × quantity. A foot is 12 inches, a yard is 3 feet, a meter is 3.280839895 feet, and a centimeter is 0.032808399 feet. The default 12 × 10 × 8 × 1 is 960.00 cubic feet.
Cubic inches = cubic feet × 1,728. Cubic yards = cubic feet ÷ 27. Cubic meters = cubic feet × 0.028316846592. Liters = cubic meters × 1,000. The displayed lines are rounded to two decimals. 960 ÷ 27 is 35.555…, so the yard line reads 35.56.

Cubic feet questions
How many cubic feet are in a 12 by 10 by 8 room?
Leave length at 12 ft, width at 10 ft, height at 8 ft, and quantity at 1. Cubic feet reads 960.00. That is 12 × 10 × 8. The room is the full box. Doors and windows are not subtracted.
How many cubic inches is 960 cubic feet?
Cubic inches reads 1,658,880.00. One cubic foot is 12 × 12 × 12 = 1,728 cubic inches, and 960 × 1,728 = 1,658,880.
How many cubic yards and liters is that room?
Cubic yards reads 35.56. Cubic meters reads 27.18. Liters reads 27,184.17. Cubic yards = 960 ÷ 27. One cubic foot is 0.028316846592 cubic meters, so 960 cubic feet is 27.184 cubic meters, which rounds to 27.18. Liters are that volume times 1,000.
What if I need two of those rooms?
Set quantity to 2. Cubic feet reads 1,920.00. Cubic inches reads 3,317,760.00. Cubic yards reads 71.11. Cubic meters reads 54.37. Liters reads 54,368.35. Quantity multiplies the one box.
How do I enter a box in inches?
Set length to 48 in, width to 24 in, and height to 18 in. Quantity stays 1. Cubic feet reads 12.00. Cubic inches reads 20,736.00. Cubic yards reads 0.44. Cubic meters reads 0.34. Liters reads 339.80. 48 × 24 × 18 = 20,736 cubic inches, and 20,736 ÷ 1,728 = 12 cubic feet.
Can each side use a different unit?
Yes. Length, width, and height each have feet, inches, yards, meters, and centimeters. A 12 ft length, a 120 in width, and a 2.4384 m height is the same 12 × 10 × 8 ft box, so the cubic feet still read 960.00.
Is this the cubic yard calculator?
No. This page starts from cubic feet for a box or a room, then shows cubic inches, cubic yards, cubic meters, and liters. The cubic yard calculator is the pad or area with a depth, including a circle and a triangle. It does not take a quantity of boxes.
