Questions people ask
How many square feet are there in an acre, guntha and bigha?
One acre is 43,560 sq ft, one guntha is 1,089 sq ft (a 40th of an acre) and one cent is 435.6 sq ft. Bigha is different in every state, so this tool lists two common sizes and tells you which: Uttar Pradesh (3,025 sq yd) and West Bengal (1,600 sq yd). Check the size written in your own land record before buying or selling.
Are KB, MB and GB here 1,000 or 1,024 bytes?
Both are given and labelled. KB, MB, GB and TB use 1,000 (how storage is sold). KiB, MiB, GiB and TiB use 1,024 (how many operating systems count). That is why a 500 GB drive shows about 465 GiB.
Why does the converter show a month and a year in seconds?
A month is taken as 30.4375 days and a year as 365.25 days, the long-run averages. For exact calendar gaps use the date difference calculator.
How is temperature converted?
Temperature uses formulas, not a ratio: F = C x 9/5 + 32 and K = C + 273.15. The tool converts through Kelvin so any pair works.
