Metres to feet, kilograms to pounds, Celsius to Fahrenheit, gigabytes to megabytes — whenever two measurement systems collide, this page sorts it out instantly. Free, precise, and no sign-up.
Choose the measurement type — length, weight, temperature, volume, speed, or data.
Type the number and select the units you're converting from and to.
Conversion happens instantly, with enough decimal places for practical use.
Metres, feet, inches, kilometres, miles; for furniture from overseas stores, DIY plans, and running distances.
Kilograms, pounds, ounces, grams, stones; for luggage limits, gym plates, and shipping.
Celsius, Fahrenheit, Kelvin; for US recipes, weather abroad, and science homework.
Litres, gallons, millilitres, fluid ounces; for fuel economy comparisons and imported product sizes.
Km/h, mph, knots; for overseas driving and following international sport.
KB, MB, GB, TB; for storage planning and download estimates.
A US gallon (3.79 L) is smaller than a UK gallon (4.55 L), and pints differ too — always check which standard your source uses.
If a calculation has several steps, keep the decimals until the end; rounding early compounds the error.
The classic conversion error is dividing when you should multiply. If 10 kg comes out as 4.5 lb rather than 22 lb, you've gone the wrong way.
Storage marketing uses 1000-based units while operating systems often report 1024-based ones — that's why a "1 TB" drive shows as roughly 931 GB.
They use standard international conversion factors, accurate to more decimal places than everyday tasks need.
Drive manufacturers count 1 TB as 1000⁴ bytes, while operating systems often count in 1024-based units. Nothing is missing.
In everyday use they're interchangeable. Strictly, mass is the amount of matter (kg) and weight is the force gravity exerts on it.
No — everything runs in your browser, with nothing to install.
Yes, completely free with no usage limits.
A unit converter looks simple on the surface. You type a number, pick two units, and get an answer. But behind that instant result is basic algebra that anyone can understand.
Every unit conversion relies on a conversion factor — a fixed number showing how many units of one measurement equal one unit of another. For example, one kilometer equals 0.621371 miles. To convert km to miles, multiply: distance in km × 0.621371 = distance in miles.
Some units are built from more than one base unit. Area is length multiplied by length, so converting an area unit means squaring the linear conversion factor. Since 1 meter = 3.28084 feet, 1 square meter is not 3.28084 square feet — it's 3.28084 squared, about 10.7639 square feet.

Mass is the amount of matter in an object, measured in kilograms. It does not change regardless of location. Weight is a force caused by gravity pulling on that mass. For daily tasks this distinction rarely matters, but in physics or engineering contexts, mixing them up can lead to real errors.
A single conversion using a rounded factor is usually fine, but chaining several conversions together lets small rounding errors compound. The safest approach is to keep full precision through every intermediate step and round only the final answer.
A fixed ratio that tells you how many units of one measurement equal one unit of another, such as 1 kilometer equaling 0.621371 miles.
Area is length × length, so its factor must be squared; volume is length × 3, so its factor must be cubed.
No. Mass is constant amount of matter; weight is the force gravity exerts on it, which changes with local gravity.
Usually caused by rounding a conversion factor too early rather than using full precision throughout.
Yes — this converter runs entirely in your browser using stored standard conversion factors.
