The prefix "nano" means ten to the power minus 9. A meter therefore has 10 to the power 9 nanometers; a number which in English is usually called a "billion". The same conversion applies to other places where the prefix "nano" appears - for example, second versus nanosecond.

The nano- prefix means "× 10^-9"

→ 0.1535 nm = 0.1535 × 10^-9 m = 1.535 × 10^-10 m
