0.045 cm 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 0.045 Centimeters we have to multiply 0.045 by 10000000 and divide the product by 1. So for 0.045 we have: (0.045 × 10000000) ÷ 1 = 450000 ÷ 1 = 450000 Nanometers
So finally 0.045 cm = 450000 nm
