Unit Converter

How to use the Unit Converter

1. Pick a measurement category from the tabs — length, weight, temperature, volume, area, speed, time or data storage.
2. Choose the unit you are converting from and type in a value.
3. Choose the unit you want the answer in; the result updates instantly as you type.
4. Use the swap button to reverse the direction, and check the common-conversions table for quick reference figures.

Why use ZillaKit's Unit Converter?

A good unit converter has to be both broad and exact, and that is what this tool is built for. Every conversion is anchored to an SI base unit — meters for length, kilograms for mass, liters for volume, square meters for area, meters per second for speed, seconds for time and bytes for data — using the internationally agreed conversion factors, so a mile is exactly 1,609.344 meters and a pound is exactly 0.45359237 kilograms rather than a rounded approximation. Temperature is handled with the proper formulas rather than a simple multiplier, because Celsius, Fahrenheit and Kelvin do not share a common zero. Data storage lets you switch between decimal units (kilobyte, megabyte, gigabyte in powers of 1000) and binary units (kibibyte, mebibyte, gibibyte in powers of 1024), which is a distinction that trips up a lot of people. Everything runs instantly in your browser with plain JavaScript, so there is no upload, no signup, no waiting and no limit on how many conversions you make. Whether you are cooking, studying, shipping, coding or travelling, you get an accurate answer the moment you type.

FAQ

How accurate are the conversions?

All conversions use exact, internationally standardised factors relative to an SI base unit, so results are as precise as the number of digits shown. For example, 1 mile equals exactly 1.609344 kilometers and 1 inch equals exactly 2.54 centimeters.

What is the difference between MB and MiB?

A megabyte (MB) is 1,000,000 bytes using the decimal SI convention, while a mebibyte (MiB) is 1,048,576 bytes (1024 x 1024) using the binary convention. Operating systems often report storage in binary units even when they label them "MB", which is why a "1 GB" drive can look smaller than expected.

Why can't I just multiply temperatures?

Because temperature scales have different zero points, you cannot convert them with a single multiplier. Celsius to Fahrenheit uses multiply by 9/5 then add 32, and Celsius to Kelvin adds 273.15. This tool applies the correct formula automatically.
