MS Excel: To convert Acres.Guntas (example 1.20, which is 1 acre and 20 guntas),
you need to enter your number (1.20) in cell A1, then in cell B1 enter
this formula =(((A1-INT(A1))*100)*0.025)+INT(A1)
You will see the numbers in fractions of acres in cell B1, after that it is very easy to add all the B cells.
