About the builder unit converter
Our free unit converter is built for UK trades. Switch between metric and imperial in seconds when you are pricing a job, reading a plan or quoting against an old specification. Coverage includes length (mm, cm, m, inches, feet, yards), area (m², ft², yd², acres), volume (litres, m³, ft³, yd³, UK gallons), weight (kg, tonnes, pounds, stone, 25 kg bags) and temperature (°C to °F).

Need to convert square metres to square feet for a floor plan, or cubic metres of concrete into cubic yards for a ready-mix quote? The converter runs every category in real time, so you can flip between metric take-offs and imperial bill-of-quantity rates without leaving the page. Use the swap button to reverse a conversion without retyping the numbers.

Frequently asked questions
- How accurate is the converter?
- Results are rounded to four significant figures, which is accurate enough for quoting and ordering building materials.
- Can it convert tonnes to cubic metres?
- No. That conversion needs the material density, which varies between aggregates, sands and concrete.
- What categories are supported?
- Length, area, volume, weight, pressure and temperature are all built in.
- Can I swap the from/to units?
- Yes. Use the swap button to reverse a conversion without retyping the value.
- Does it work on mobile?
- Yes. The converter is responsive and works on phones, tablets and desktops without any app install.
