Construction tools for US contractors

Every tool has a dedicated US URL, so browsing never sends you back to the UK site. US-reviewed tools use measurements and terminology expected on American jobsites.

Imperial-first. Feet, inches, square feet and cubic yards where the tool is US-reviewed.

No false conversions. UK tax, law and standards tools are paused instead of relabeled.

3 free tools. One account works across both regional versions.

What “US-reviewed” means

11 tools have completed the US review. Measurement tools in that group accept US customary inputs and show feet, inches, square feet, cubic yards, pounds, gallons or Fahrenheit where the calculation calls for them.

Every other tool keeps its US URL but shows a review notice. That includes tools tied to UK tax, law, product sizes, building regulations or British Standards; they never silently present UK guidance as American guidance.

Fully localized today: 11. More are being converted in priority order from real US usage data.
