1000 mm to nm 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 Nanometers are 1000 Millimeters we have to multiply 1000 by 1000000 and divide the product by 1. So for 1000 we have: (1000 × 1000000) ÷ 1 = 1000000000 ÷ 1 = 1000000000 Nanometers
So finally 1000 mm = 1000000000 nm
