Indian land units are included under Area, but note that bigha, katha and marla vary considerably by state — the bigha here is the common 1,600 square yard definition. Always confirm the local definition before relying on a land conversion.
Frequently Asked Questions
Which Indian land units are supported?
Bigha, guntha, cent, square yard (gaj), acre and hectare, alongside the metric and imperial units. Land measurement in India is where most converters fall short.
Why does bigha vary so much?
Because it was never standardised. A bigha ranges from about 1,600 square yards in parts of north India to over 3,000 in others, and some states do not use it at all. This tool uses the common 1,600 square yard definition — confirm the local one before relying on it for a property transaction.
How do I convert temperature?
Select the Temperature family. Temperature is handled differently from other units because the scales have different zero points, so a simple multiplication would give the wrong answer.
Is a kilobyte 1000 or 1024 bytes?
This tool uses 1024, the binary convention operating systems apply. Storage manufacturers use 1000, which is why a 1 TB drive shows as roughly 931 GB in Windows.
