A nanometer is 10^-9 meter, whereas a micrometer is 10^-6 meter. So a nanometer is 1000th of a micrometer. A nanometer is smaller.
A nanounit means one-billionth of the same unit. (10-9) 1 nanometer = 1 billionth of a meter 1 nanogram = 1 billionth of a gram etc.
1 gigameter = 1018 nanometers
a nano meter is one billionth of a meter 15 nm = .000000015 meter = 1.5 x 10 to the -8 meter
