At a glance
Cubic Inches to Cubic Yards
Divide cubic inches by 46,656 to get cubic yards. Multiply cubic yards by 46,656 for cubic inches. One yard is 36 inches, and 36³ = 46,656.
Conversions
Convert cubic inches to cubic yards
yd³ = in³ ÷ 46,656
in³ = yd³ × 46,656
The input must already be a volume. If you have three measurements in inches, multiply length × width × depth first, then divide their product by 46,656. A single length in inches is not enough.
For example, a box 36 inches along every edge holds 46,656 cubic inches, or one cubic yard. A 12 inch cube holds 1,728 cubic inches, which is one cubic foot or one twenty seventh of a cubic yard.

Small volumes need enough decimal places to remain useful. The converter displays small positive values with significant digits instead of rounding them immediately to zero. Calculations retain precision before display.

Using inch measurements for concrete or a container
If all form dimensions are in inches, multiply them before using this converter. Alternatively, the main calculator accepts each dimension with its own unit, so you can combine feet for a slab length and inches for thickness without doing the conversion yourself.
The reverse conversion is useful when a specification uses cubic inches. Keep cubic inches, square inches, and ordinary inches separate: they measure volume, area, and length respectively.
Common questions
Cubic Inches to Cubic Yards questions, answered.
How many cubic inches are in one cubic yard?
Exactly 46,656 cubic inches. The cube has a 36 inch edge, and its volume is 36 × 36 × 36.
Is a cubic yard equal to 36 inches?
A one cubic yard cube has edges of 36 inches. Its volume is 46,656 cubic inches. An edge length and a volume are different measurements.
Can I convert cubic inches to yards of concrete?
Yes, if yards means cubic yards of finished concrete. Divide the cubic inch volume by 46,656, then consider any ordering allowance separately.
