What is the Unit Converter tool?
This unit converter turns one measurement into another the instant you type — more than 50 units across eight categories: length, weight, temperature, area, volume, speed, data and time. Convert kg to lbs for a gym plan or a recipe, cm to inches for a screen size, °C to °F for the weather abroad, or gigabytes to megabytes when a download looks suspiciously large. Pick a category, choose the two units, and the result updates live, with a one-unit equivalence line underneath so you can sanity-check the rate at a glance.
All the math runs client-side in your browser. Nothing you enter is sent anywhere, there is no account and nothing to install, and once the page has loaded it keeps working offline — a genuinely free measurement converter that is ready whenever you are, on any device.
Compared with the long-running conversion sites, the difference here is focus: a clean, phone-first layout with big touch targets instead of dense desktop tables and ad columns. The swap button flips the direction in one tap, so checking both ways — miles to kilometres, then kilometres back to miles — takes seconds. And if what you need to convert is money rather than measurements, Carbide's currency converter sits right next to this tool.
How to use the Unit Converter
- Choose a category chip — length, weight, temp, area, volume, speed, data or time.
- Pick the unit you are converting from in the first selector.
- Type the value — the converted result appears instantly as you type.
- Pick the target unit in the second selector to change what you convert to.
- Tap the swap button to flip the direction, and check the equivalence line to see what one unit equals.
Frequently asked questions
How do I convert kg to lbs?
One kilogram is about 2.2046 pounds (1 lb = 0.4536 kg exactly, by definition). Choose the Weight category, set kg as the from-unit and lb as the to-unit, and type your value — 70 kg comes out as about 154.3 lb.
How do I convert cm to inches?
One inch is exactly 2.54 cm. Choose Length, convert from cm to in, and type the value — 170 cm is about 66.9 inches. Tap swap to go the other way.
How do I convert Celsius to Fahrenheit?
The formula is °F = °C × 9/5 + 32, so 25 °C is 77 °F. The Temp category applies it for you in either direction, and Kelvin is supported too.
Which units does it support?
Eight categories with 50+ units: length (m, km, cm, mm, mi, yd, ft, in, nautical miles), weight (kg, g, mg, tonnes, lb, oz, stone), temperature (°C, °F, K), area (m², km², hectares, acres, ft², yd², mi²), volume (L, mL, m³, gallons, quarts, pints, cups, fl oz), speed (m/s, km/h, mph, knots, ft/s), data (bytes through TB, plus bits) and time (ms to weeks).
Is the unit converter free?
Yes — completely free, with no sign-up, no install and no limit on how many conversions you run.
Is my data private, and does it work offline?
Both. Every conversion is computed in your browser — nothing is sent to a server — and once the page has loaded it works without an internet connection.
How is this different from unitconverters.net or calculator.net?
Those sites cover many more specialist units — energy, pressure, force and so on. This converter deliberately covers the everyday eight categories with a faster, cleaner page built for phones. If your conversion is a common one, you will get the answer here with less scrolling and no clutter.
