Frequently Asked Questions

What's the difference between metric and imperial units?

The metric system (used by most of the world) is a decimal-based system using units like meters, grams, and liters. The imperial system (used primarily in the United States) uses units like feet, pounds, and gallons. Our tool allows you to convert between both systems seamlessly.

What is Kelvin and where is it used?

Kelvin (K) is the base unit of temperature in the International System of Units (SI). It's an absolute temperature scale, meaning 0 K is absolute zero—the point where all thermal motion ceases. Kelvin is primarily used in scientific and engineering contexts.
