What is a Unit Converter?
A unit converter is a tool that translates measurements between different units of the same physical quantity: converting kilometers to miles, kilograms to pounds, Celsius to Fahrenheit, and so on. Developers, engineers, scientists, and everyday users constantly encounter values in units that differ from what they need, making a fast, reliable converter essential.
CodeHelper's Unit Converter supports 80+ units across 10 categories including a unique CSS units category (px, rem, em) that is invaluable for front-end developers.
Supported Categories
- Length: km, m, cm, mm, miles, yards, feet, inches: and more.
- Weight & Mass: tonnes, kg, g, mg, pounds, ounces, stone.
- Temperature: Celsius, Fahrenheit, Kelvin with exact conversion formulas.
- Speed: m/s, km/h, mph, knots, ft/s.
- CSS Units: px, pt, rem, em, percentages and viewport units (vw, vh), with configurable root font size, context font size and viewport dimensions for accurate front-end calculations.
- Energy, Power, Pressure, Area, Volume: Complete scientific and engineering unit sets.
How to convert units
- Select a category (e.g., Length, Temperature, CSS Units).
- Choose the source unit and enter a value.
- Select the target unit to see the converted result instantly.
- Star units as favorites for quick access in future sessions.
- View all conversions at once with the "Show All" mode.
Whether you are converting metric to imperial for a recipe, calculating CSS pixel values for a design spec, or doing engineering calculations, this free unit converter handles every measurement you encounter in development and daily work.
Weight conversion reference: kg, lbs and grams
Weight is the conversion people look up most, so here are the exact factors this tool uses. One kilogram equals 2.20462 pounds, and one pound equals 0.453592 kilograms. To go from kg to lbs, multiply by 2.20462; to go from lbs to kg, divide by 2.20462 (or multiply by 0.453592).
| Kilograms | Pounds |
|---|---|
| 1 kg | 2.20 lb |
| 5 kg | 11.02 lb |
| 10 kg | 22.05 lb |
| 20 kg | 44.09 lb |
| 50 kg | 110.23 lb |
| 100 kg | 220.46 lb |
For smaller masses, one kilogram is 1,000 grams, so 250 grams is 0.25 kg and 500 grams is 0.5 kg. Enter any value above to get the precise figure instead of the rounded reference.
Frequently Asked Questions
How many pounds are in a kilogram?
One kilogram equals 2.20462 pounds. To convert kilograms to pounds, multiply by 2.20462; to convert pounds to kilograms, divide by 2.20462 (or multiply by 0.453592). For example, 10 kg is 22.05 lb and 50 kg is 110.23 lb.
What is the difference between metric and imperial units?
Metric (SI) units, used by most of the world, are decimal-based: metres, kilograms, litres, with prefixes like kilo and milli. Imperial units, common in the US and UK, use feet, pounds and gallons with non-decimal factors. This converter handles both and translates between them, which is why it is handy for recipes, travel and engineering.
Can this tool convert CSS and developer units?
Yes. Besides everyday measurements like length, weight and temperature, the CSS Units tab converts pixels, points, rem, em, percentages and viewport units (vw, vh), with configurable root font size, context font size and viewport dimensions, which makes it useful for design specs and front-end work. For data sizes such as bytes, KB and MB use the Byte Size Converter, and for timestamps and durations the Time Converter, both on CodeHelper.
