Unit Converter
Try typing something like 56.3 m to ft or just m to ft.
Why ConvertUnits.engineer?
Many online unit converters handle only basic measurements. Engineering work often requires conversions between less common units, such as specific weight, pressure, density, and flow rate. This site was created by a practicing engineer to support real-world calculations where accuracy and consistency matter.

Unit Conversion FAQ
Quick answers to common unit conversion questions.
Pick the unit type, select a From unit and a To unit, enter a value, and the calculator converts instantly. For best results, confirm you selected the correct quantity (for example pressure vs stress) before copying the output.
Many unit conversions involve exact ratios that do not map cleanly between systems. The calculator may display additional decimals, but you should round the final value to match the precision of your input data and the engineering method you are using.
No. Converting units changes the representation of a value, not the accuracy of the underlying measurement or method. Report a reasonable number of digits based on the uncertainty of your inputs.
Mass is the amount of matter and is commonly reported in kilograms, grams, or slugs. Weight is a force and is commonly reported in newtons, pounds-force, or kips. Make sure you are using the correct quantity for your calculation.
Gauge pressure is measured relative to atmospheric pressure. Absolute pressure is measured relative to a vacuum. A unit converter does not know which one you intend, so confirm the pressure reference before converting or reporting results.
Many conversion factors are exact by definition (for example inch to meter). Others depend on conventions or reference conditions. When in doubt, verify the standard used for your project or specification.
Yes. After selecting a unit type and units, you can bookmark the page URL. Some pages also support passing a value in the URL to prefill the calculator for quick reuse.
Many industries still use legacy imperial units, especially in the U.S., while standards and global collaboration often use SI. Converters help reduce friction when combining drawings, reports, and vendor data in different unit systems.
