20 mph to kn 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 Knots are 20 Miles per Hour we have to multiply 20 by 50292 and divide the product by 57875. So for 20 we have: (20 × 50292) ÷ 57875 = 1005840 ÷ 57875 = 17.379524838013 Knots
