Frequently Asked Questions

Which units do US construction projects use?

US construction runs on imperial: feet and inches for length, square feet for area, cubic yards for concrete, pounds for weight, and psi for strength. Metric appears on imported materials and international specs.

Why does construction unit conversion matter?

A 0.5-inch error on a footing or the wrong psi on a concrete spec can cost thousands and fail inspection. Using the unit your drawings and codes expect prevents costly mistakes.

Is this the same converter as the generic tools?

This hub shows only the converters used on US construction sites — length, area, pressure, weight, and temperature pairs relevant to building. The same exact NIST factors apply to every converter.
