Convert feet to meters, free and instant.
Convert between common units of length, weight, temperature, and volume — pick a category, choose your "from" and "to" units, and the result updates instantly as you type.
Length, weight, and volume conversions use fixed, universally standard ratios (an inch is always exactly 2.54cm, a pound is always exactly 0.45359237kg) — these are official definitions, not approximations. Temperature uses the actual conversion formulas between Celsius, Fahrenheit, and Kelvin rather than a simple ratio, since these scales don't share a common zero point.
Nothing here touches a server — every conversion is basic arithmetic that happens instantly in your browser.
Exact — length, weight, and volume conversions use official, fixed definitions (like 1 inch = exactly 2.54cm), not rounded approximations. Displayed results are rounded for readability, but the underlying math uses the full precision value.
Celsius, Fahrenheit, and Kelvin don’t share a common zero point, so converting between them needs a formula (like Celsius × 9/5 + 32 for Fahrenheit) rather than a simple multiplication ratio the way length or weight can.
US cups, US gallons, and US quarts are the American customary definitions, which differ from UK imperial measurements of the same name — worth checking which your recipe or source actually means before assuming they match.
