Indian Units for Length & Area Measurement

Most of the indians still use imperial measurement system, though it is unofficial and is probably illegal. I had tough time in understanding these units as I am more familiar with SI units. Finally decided that I would need to master these units. In the process whatever the information I have collected, decided will publish it for others to use.

The basic unit of length is the yard (yd)

1 yard = 0.9144m

1 inch = 1/36 yd
1 foot = 1/3 yd

1 rod = 5 1/2 yd
1 furlong = 220 yd
1 mile = 1,760 yd

1 acre = 4,840 square yards or 160 square rods
