Frequently Asked Questions
Is the Unit Converter free?
Yes, completely free. No sign-up, no limits, no subscription. All conversions happen instantly in your browser.
Does it work offline?
Once the page loads, conversions happen entirely client-side — no network requests are made during calculation. Your browser just needs to load the page once.
How accurate are the conversions?
All conversion factors are based on internationally accepted standards (SI system, NIST, and other authoritative sources). Results are computed with full floating-point precision and displayed up to 10 significant digits.
What units are supported?
Weight, length, temperature, volume, area, speed, time, and data storage — covering the most commonly needed conversions. Each category includes both metric and imperial units.
Can I convert temperature?
Yes. Celsius, Fahrenheit, and Kelvin are all supported. Temperature uses the correct offset formulas rather than simple multiplication, so conversions are accurate.
How do I convert kg to lbs?
Type your value in the search bar above — for example, '75 kg to lbs' — and the result appears immediately. Or go directly to the kg to lbs converter. For reference: 1 kilogram equals approximately 2.20462 pounds.
Can I convert data storage units like GB to TB?
Yes. The data storage category covers bits, bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes — plus binary units (kibibyte, mebibyte, gibibyte, tebibyte). Useful for comparing file sizes, SSD specs, or cloud storage plans.
