How it works

1

Pick the type

Length, area, volume, or weight.

2

Enter value and units

The number and what it is measured in.

3

Choose the target unit

The converted value appears instantly.

A fast converter for the units construction actually uses: length (in, ft, yd, mm, cm, m), area (in², ft², yd², cm², m²), volume (in³, ft³, yd³, cm³, liters, m³, US gallons), and weight (oz, lb, g, kg, US tons, tonnes). Pick the category, enter a value, choose the units — the conversion is instant.

Most drawings mix imperial and metric these days — an imported fixture schedule in mm on a 1/4" plan, a spec in liters on an imperial set. This handles the translation without a lookup table.

Questions, answered

About 92.9 m² — multiply square feet by 0.0929. The reverse (m² to ft²) multiplies by 10.764.
