About Zunqari

What Zunqari does

Zunqari converts measurements across ten categories: length, weight and mass, temperature, area, volume, speed, time, digital storage, energy and power. Type a value, pick two units, and the result appears as you type.

How results are calculated

Every unit is defined from its official definition rather than a rounded approximation. An inch is exactly 2.54 cm, a pound is exactly 0.45359237 kg, and a US gallon is exactly 3.785411784 liters. Calculations use full double-precision arithmetic, and rounding only happens when the result is displayed.

Where a unit name means different things in different places, Zunqari lists each version separately: US and UK gallons, decimal gigabytes and binary gibibytes, mechanical and metric horsepower.

Private by design

The converter runs entirely in your browser. The numbers you enter are not sent to a server, and you don’t need an account. The privacy policy explains the details, including how contact form messages are handled.
