The formulas for conversion are represented below:
nm = km x 1012
Example: 30 kilometers in meters:
nm = km x 1.000.000.000.000
nm = 30 x 1.000.000.000.000
nm = 3x10-13
km = nm / 1012
Example: 1500 Nanometers in kilometers:
km = nm / 1.000.000.000.000
km = 1500 / 1.000.000.000.000
km = 1,50x10-9
Considering that 1 kilometer is equivalent to 1012 nanometers, you can use a rule of three to obtain that 1.5 km equals 1.5x1012 nm.
1 km - 1012 nm
1,5 km - x
Apply the rule of three and get:
x km = 1,5 kmnm
x = 1,5x1012 nm
If every 1,000,000,000,000 Nanometers we have 1 kilometer, just divide the number of Nanometers (100) by 1000, so you will get that 100 m equals 0.1 km. Observe the calculation below:
km = nm / 1.000.000.000.000
Km = 100 / 1.000.000.000.000
km = 1x10-10
