Convert cubic inches or cubic feet to milliliters, liters, cubic centimeters, or cubic meters, and back with a single volume value.
Assumptions Assumptions
- Conversions are volume-to-volume only—no density or mass conversions.
- Exact definitions used: 1 in = 2.54 cm (exact), so 1 in³ = (2.54)³ cm³ = 16.387064 mL (exact).
- Related units: 1 ft³ = 28,316.846592 mL; 1 L = 1000 mL; 1 m³ = 1,000,000 mL; and 1 cm³ = 1 mL.
- Values shown may be rounded for readability; calculations use full-precision constants.
When to Use This Calculator
- Converting 3D volumes of containers or shipments between imperial and metric systems.
- Engineering, packaging, or science tasks that need in³ ↔ mL (or L/cm³/m³) quickly.
- Standardizing specifications across regions that use different volume units.
Input Definitions
- Cubic Inches — choose in³ or ft³; 1 ft³ = 1728 in³ = 28,316.846592 mL.
- Milliliters — choose mL, L (1000 mL), cm³ (1 mL), or m³ (1,000,000 mL).
- Conversions — mL = in³ × 16.387064; in³ = mL ÷ 16.387064; and 1 cm³ = 1 mL.
