How to use
Choose a category (length, weight, temperature, area, volume, speed, time or data), enter a value, and pick the from and to units. Conversion goes through the category base unit: result = value × from-factor ÷ to-factor. The factor is shown under the result.
Factors are exact definitions where they exist: 1 inch = 25.4 mm exactly, 1 mile = 1.609344 km, 1 pound = 0.45359237 kg. Temperature is the exception and uses formulas instead: °F = °C × 9/5 + 32 and K = °C + 273.15.
Notes
One tsubo is converted as 3.305785 m² and one tatami as 1.62 m² (the Chūkyō-ma size). Real tatami sizes differ by region, so treat real-estate figures as approximate. Kilobytes (KB, 1,000 bytes) and kibibytes (KiB, 1,024 bytes) are kept as separate units. All conversions run entirely in your browser.
FAQ
What is the difference between KB and KiB?
A kilobyte (KB) is 1,000 bytes; a kibibyte (KiB) is 1,024 bytes. Storage products are usually labeled in KB units while operating systems often report KiB units, which is why the same capacity can appear as different numbers.
