[X] hr = 0.016666666666667 × [Y] min

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

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

45 min to hr 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 Hours are 45 Minutes we have to multiply 45 by 1 and divide the product by 60. So for 45 we have: (45 × 1) ÷ 60 = 45 ÷ 60 = 0.75 Hours

So finally 45 min = 0.75 hr
