## How many nanometers (nm) are in a kilometer (km)? What is the formula for how to convert nanometers to kilometers (nm to km)?

**1 nanometer (nm) = 0.000000000001 kilometer (km)**

So we can say that there is 0.000000000001 kilometer in 1 nanometer.

This means that the multiplication conversion factor to convert a quantity expressed in a nanometer unit of measurement to an equivalent quantity expressed in a kilometer unit of measurement is 0.000000000001.

Inversely (or reciprocally),

**1 kilometer (km) = 1,000,000,000,000 nanometers (nm)**

So we can say that there are 1,000,000,000,000 nanometers in 1 kilometer.

This means that the division conversion factor to convert a quantity expressed in a nanometer unit of measurement to an equivalent quantity expressed in a kilometer unit of measurement is 1,000,000,000,000.

Knowing this inverse mathematical relationship between the two conversion factors and their reciprocal operations, we can derive two formulas to calculate and convert a quantity of length expressed in nanometers to an equivalent quantity of length expressed in kilometers (nm to km). Both formulas will yield the same result. The formulas are:

km = nm × 0.000000000001→ This is the formula based on the multiplication conversion factor.

and

km = nm ÷ 1,000,000,000,000→ This is the formula based on the division conversion factor.

For example, if you have a length of 650,000,000 nanometers that you want to convert to kilometers, you would use either of the two formulas as follows:

km = 650,000,000 nm × 0.000000000001 = 0.00065 km

km = 650,000,000 nm ÷ 1,000,000,000,000 = 0.00065 km

So, the result is the same using either formula, which is 0.00065 kilometers.
