Unit Converter

Convert between length, weight, temperature, volume, speed, and data units. 100+ unit pairs instantly.

Converting between metric and imperial — or between data sizes and speeds — slows down any workflow. This converter handles length, weight, temperature, volume, speed, and data units with 100+ unit pairs. Every conversion updates in real time. All math happens locally on your device.

Shipping and logistics quotes collide with the metric-imperial divide constantly. An overseas supplier quotes a 2.4 kg parcel, the courier form wants pounds, and the freight estimate is in cubic feet while your box measurements are in centimeters. Converting between those units at the point of filling out the form avoids the arithmetic slip that turns a cheap shipment into an unexpected surcharge. With length, weight, and volume all covered in one place, the whole quote process stays consistent without flipping between separate conversions.

Temperature and data-size conversions trip up far more professionals than they admit. A process spec written in Fahrenheit meets a controller programmed in Celsius, and a storage quote in decimal terabytes meets an operating system that reports gibibytes. Getting the two scales confused has real consequences, from ruined batches to underestimated capacity. Converting with the right unit pair, including decimal-versus-binary data units and both temperature scales, resolves these mismatches on the spot. It is the reliable cross-check when two systems disagree simply because they use different conventions.

FAQ

Frequently asked questions

Everything you need to know about unit converter.

Which measurement categories are supported?

Five categories: length, mass, temperature, volume, and speed. Together they cover 33 units, from millimeters to miles, milligrams to tons, milliliters to gallons, and m/s to knots.

Are the temperature formulas correct?

Yes. Fahrenheit converts with (C x 9/5) + 32 and Kelvin with C + 273.15, and the tool displays the exact formulas under the result so you can verify any conversion.

How precise are the results?

Values are rounded to 4 decimal places for readability, and the conversion table shows the equivalent value in every unit of the selected category at once.

Can I copy individual conversions?

Yes. Every row in the conversion table has a copy button that copies the value together with its unit label, for example '1000 m', straight to the clipboard.

Is my data private?

Completely. The converter is pure client-side math running in your browser; the value you enter is never transmitted or stored anywhere.
