516 kn to mach 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 Mach are 516 Knots we have to multiply 516 by 463 and divide the product by 298170. So for 516 we have: (516 × 463) ÷ 298170 = 238908 ÷ 298170 = 0.80124761042358 Mach
So finally 516 kn = 0.80124761042358 mach
