Here is how the Rate of Interest(SI) calculation can be explained with given input values -> 1.600E-9 = (1000*100)/(1000000*62500000).

### FAQ

What is Rate of Interest(SI)?
Rate of Interest(SI) is calculated on the principal amount for the due period. It is generally expressed as a percent per year and is represented as I=(SI*100)/(A*T) or Rate of interest=(Simple Interest*100)/(Principal Investment Amount*Time). Principal Investment Amount is most commonly used to refer to the amount borrowed or the amount still owed on a loan, separate from interest, Simple Interest is used to calculate the interest charged on a principal amount and Time is used to calculate the amount that has a simple interest.
How to calculate Rate of Interest(SI)?
