Measure & convert

Unit Converter / Quick Tools

Convert jobsite measurements without mixing length, area, volume or weight. Use fractional values and get the conversion factor alongside the result.

How to use the unit converter / quick tools

Choose the measurement category before selecting units. Area factors are squared and volume factors are cubed; a linear conversion cannot be applied unchanged to square or cubic units. The tool keeps full precision and rounds only the displayed answer.

Formula

Converted value = input value × source unit factor ÷ target unit factor
1 ft = 0.3048 m exactly
1 ft² = (0.3048)² m²; 1 ft³ = (0.3048)³ m³

Assumptions & scope

  • Feet refer to international feet, not historical US survey feet.
  • Gallons are US liquid gallons. Tons are US short tons; metric tonnes are listed separately.
  • Weight-to-volume conversion is intentionally not offered here because it requires a material density. Use the Gravel Calculator for that calculation.
ON THE JOB / WORKED EXAMPLE

A calculation you can check

Convert 2½ cubic yards to cubic feet: 2.5 × 27 = 67.5 ft³. Convert 5 ft 7½ in to meters: (5 × 12 + 7.5) × 0.0254 = 1.7145 m.

Calculation methodology

Conversion factors follow NIST SI conversion tables. Units are restricted to compatible dimensions, and invalid or empty values produce an explicit error.

Length conversions use the NIST SI conversion factors. See our calculation and editorial standards for precision, validation and limitations.

Common questions

Can I enter fractions?

Yes. Enter a simple fraction such as 3/8 or a mixed number such as 7 1/2. For length, you can also enter 5' 7 1/2" or an explicit suffix such as 12 in.

Why can’t I convert cubic yards directly to tons?

Volume and mass measure different things. Their relationship depends on material bulk density, which can vary substantially. Use the Gravel Calculator and a supplier density.

Are the conversions exact?

The international foot, inch, yard and pound conversion factors used here are defined exactly. Displayed values are rounded, and measurement uncertainty remains in your original inputs.
