Utilities calculator

Length unit converter

Transparent source-to-target length conversion with side-by-side feet and metres equivalents.

Calculator result and formula

Converted value in m: 3.048 m

Formula: Source value × source-unit-to-feet factor ÷ target-unit-to-feet factor

Formula ID: UTIL-LENGTH-CONVERT-001 · Version 1.0.0.

Inputs

  • Value: Length value to convert Default: 10.
  • Source unit: Unit of the entered value Default: 1.
  • Target unit: Unit for the converted result Default: 2.

How this calculator works

This utility converts a stated length between feet, metres, inches and centimetres while also displaying canonical feet and metres equivalents for cross-checking.

  1. Enter the value in its known source unit.
  2. Choose the source and target units.
  3. Use the side-by-side canonical values to cross-check drawings, supplier data and calculator inputs.

Worked example: Example: 10 ft converts to 3.048 m, 120 in and 304.8 cm. The source and target units remain visible so a result never loses its measurement basis.

Assumptions and limitations

  • This tool converts linear length only.
  • All conversions pass through feet as the canonical internal unit.
  • Use the unit stated by the drawing, product label or survey source; do not mix length with area or volume units.

Common questions

Does this convert area or volume?
No. This tool converts linear length only; use a geometry calculator before converting calculated area or volume.
Why show feet and metres as well?
Construction references frequently mix systems. Canonical values make the selected conversion easier to audit.
