[X] mm = 25.4 × [Y] in

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

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

20 in to mm 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 Millimeters are 20 Inches we have to multiply 20 by 127 and divide the product by 5. So for 20 we have: (20 × 127) ÷ 5 = 2540 ÷ 5 = 508 Millimeters

So finally 20 in = 508 mm
