Frequently asked questions
Which quantities can I convert?
Length, weight, temperature, area, volume, speed, time, data storage, pressure and energy. Use the selector at the top to switch.
How accurate are the conversions?
Factors use the internationally defined values, such as 1 foot = 0.3048 m exactly. Results are shown to 10 significant figures.
Why is temperature handled differently?
Celsius, Fahrenheit and Rankine have offset zero points, so they use formulas rather than a single multiplication factor.
Are katha and bigha the same everywhere?
No. The tool uses the common Bangladesh standard of 720 ft² per katha and 20 katha per bigha; local measures can differ by district.
