[X] min = 60 × [Y] hr

where [X] is the result in min and [Y] is the amount of hr we want to convert

where [X] is the result in min and [Y] is the amount of hr we want to convert

4.5 hr to min conversion result above is displayed in three different forms: as a decimal (which could be rounded), in scientific notation (scientific form, standard index form or standard form in the United Kingdom) and as a fraction (exact result). Every display form has its own advantages and in different situations particular form is more convenient than another. For example usage of scientific notation when working with big numbers is recommended due to easier reading and comprehension. Usage of fractions is recommended when more precision is needed.

If we want to calculate how many Minutes are 4.5 Hours we have to multiply 4.5 by 60 and divide the product by 1. So for 4.5 we have: (4.5 × 60) ÷ 1 = 270 ÷ 1 = 270 Minutes

So finally 4.5 hr = 270 min
