Assumptions Assumptions
  • Pure volume-to-volume conversions; no density or weight assumptions.
  • Exact identities: 1 yd = 3 ft, 1 ft = 12 in → 1 yd^3 = 27 ft^3 = 46,656 in^3.
  • Metric links: 1 mL = 1 cm^3; 1 L = 1000 cm^3; 1 m^3 = 1,000,000 cm^3 = 61,023.7440947 in^3.
  • Converts volumes only—do not confuse cubic units with linear inches or yards.
When to Use This Calculator
  • Estimating concrete, soil, mulch, or gravel volumes from plans drawn in inches or yards.
  • Converting tank, box, or shipping volumes between US customary and metric units.
  • Checking CAD/BIM outputs (in^3, ft^3, m^3) against specifications in cubic yards.
Input Definitions
  • Cubic Inches — enter in^3 or select ft^3, cm^3, mL, L, or m^3 from the dropdown.
  • Cubic Yards — enter yd^3 or switch to ft^3, in^3, m^3, US gallons, or US quarts.
  • Key identities — yd^3 = in^3 ÷ 46,656; in^3 = yd^3 × 46,656; yd^3 = ft^3 ÷ 27; ft^3 = yd^3 × 27.

In^3 to Yards Formula

The following formulas convert cubic inches to cubic yards and back using the exact identity 1 yd^3 = 46,656 in^3.

\mathrm{yd^3} = \frac{\mathrm{in^3}}{46656}
\mathrm{in^3} = 46656\,\mathrm{yd^3}
  • 1 yd^3 = 46,656 in^3
  • 1 yd^3 = 27 ft^3
  • 1 ft^3 = 1,728 in^3
  • 1 m^3 = 61,023.7441 in^3
  • 1 US gallon = 231 in^3
  • 1 US quart = 57.75 in^3

How do you convert cubic inches to cubic yards? Divide cubic inches by 46,656; for example, 10,000 in^3 ÷ 46,656 ≈ 0.2143 yd^3.

How do you convert cubic yards to cubic inches? Multiply cubic yards by 46,656; for example, 2 yd^3 × 46,656 = 93,312 in^3.
