About Converting Nanometers to Attometers
Nanometer and Attometer both measure length. Specifically: Nanometer is 1e-9 meter units, and attometer is 1e-18 meter units.
Formula
attometers = nanometers × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 nanometer equals 1e-9 base units, and 1 attometer equals 1e-18 base units, so dividing one by the other gives the direct nanometer-to-attometer factor of 1000000000.
Simple example
1 nm × 1000000000 = 1,000,000,000 am
1 nanometer = 1,000,000,000 attometers.
Real-world example
10 nm × 1000000000 = 10,000,000,000 am
10 nanometers = 10,000,000,000 attometers.

Frequently asked questions
How many attometers are in 1 nanometer?
1 nanometer equals 1,000,000,000 attometers, using the exact defined conversion factor rather than an estimate.
How do I convert nanometer to attometer?
Multiply the nanometer value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert attometer back to nanometer?
Use the reverse factor: 1 attometer equals 1e-9 nanometers. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanometer?
Nanometer (nm) is a unit of length.
What is a attometer?
Attometer (am) is a unit of length.
Is the nanometer to attometer conversion exact?
Yes. Both nanometer and attometer are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 used above is exact to as many digits as you choose to display.
