Convert cubic inches to cubic yards (in³ to yd³), or cubic yards back to cubic inches, with cubic feet, cubic meters and US gallons as options.

Optional settings

Assumptions Assumptions
  • Pure volume-to-volume conversions; no density or weight assumptions.
  • Exact identities: 1 yd = 3 ft, 1 ft = 12 in → 1 yd3 = 27 ft3 = 46,656 in3.
  • Metric links: 1 mL = 1 cm3; 1 L = 1000 cm3; 1 m3 = 1,000,000 cm3 = 61,023.7440947 in3.
  • 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 (in3, ft3, m3) against specifications in cubic yards.
Input Definitions
  • Cubic Inches — enter in3 or select ft3, cm3, mL, L, or m3 from the dropdown.
  • Cubic Yards — enter yd3 or switch to ft3, in3, m3, US liquid gallons, or US liquid quarts.
  • Key identities — yd3 = in3 ÷ 46,656; in3 = yd3 × 46,656; yd3 = ft3 ÷ 27; ft3 = yd3 × 27.

in3 to Yards Formula

The following formulas convert cubic inches to cubic yards and back using the exact identity 1 yd3 = 46,656 in3.

yd3 = (in3) / (46656)
in3 = 46656 yd3
  • 1 yd3 = 46,656 in3
  • 1 yd3 = 27 ft3
  • 1 ft3 = 1,728 in3
  • 1 m3 = 61,023.7441 in3
  • 1 US liquid gallon = 231 in3
  • 1 US liquid quart = 57.75 in3

How do you convert cubic inches to cubic yards? Divide cubic inches by 46,656; for example, 10,000 in3 ÷ 46,656 ≈ 0.2143 yd3.

How do you convert cubic yards to cubic inches? Multiply cubic yards by 46,656; for example, 2 yd3 × 46,656 = 93,312 in3.

Example Problem

Convert 125,000 in3 to yd3.

Use the formula: yd3 = in3 ÷ 46,656.

yd3 = 125,000 ÷ 46,656 ≈ 2.6792 yd3
