About Converting Micrometers to Attometers
Micrometer and Attometer both measure length. Specifically: Micrometer is 0.000001 meter units, and attometer is 1e-18 meter units.
Formula
attometers = micrometers × 1000000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 micrometer equals 0.000001 base units, and 1 attometer equals 1e-18 base units, so dividing one by the other gives the direct micrometer-to-attometer factor of 1000000000000.
Simple example
1 um × 1000000000000 = 1,000,000,000,000 am
1 micrometer = 1,000,000,000,000 attometers.
Real-world example
10 um × 1000000000000 = 1e+13 am
10 micrometers = 1e+13 attometers.

Reverse conversion: Attometer to Micrometer
1 am × 1e-12 = 1e-12 um
1 attometer = 1e-12 micrometers.
micrometers = attometers × 1e-12

Frequently asked questions
How many attometers are in 1 micrometer?
1 micrometer equals 1,000,000,000,000 attometers, using the exact defined conversion factor rather than an estimate.
How do I convert micrometer to attometer?
Multiply the micrometer value by 1000000000000. The converter above does this instantly to whatever precision you set.
How do I convert attometer back to micrometer?
Use the reverse factor: 1 attometer equals 1e-12 micrometers. You can also use the swap control in the converter above to flip the direction instantly.
What is a micrometer?
Micrometer (um) is a unit of length.
What is a attometer?
Attometer (am) is a unit of length.
Is the micrometer to attometer conversion exact?
Yes. Both micrometer and attometer are defined by fixed standards rather than physical artifacts, so the factor of 1000000000000 used above is exact to as many digits as you choose to display.
