Frequently Asked Questions
How accurate are the conversions?
All conversion factors used are based on the international standards defined by the International Bureau of Weights and Measures (BIPM). Results are accurate to the precision of JavaScript double-precision floating-point arithmetic.
Why does temperature conversion work differently?
Unlike most units, temperature scales do not share a common zero point. Celsius and Fahrenheit require a linear formula (°F = °C × 9/5 + 32), while Kelvin is an absolute scale starting at absolute zero.
Can I convert between metric and imperial units?
Yes. The converter supports both metric (SI) and imperial/US customary units across all categories, allowing seamless conversion between systems.
What categories of units are supported?
The converter supports length, mass/weight, temperature, area, volume, speed, data storage, time, and more — covering the most common everyday and scientific conversion needs.
