How to convert meters to attometers

1 meter is equal to 1 × 10¹⁸ attometers, and 1 attometer is equal to 1 × 10⁻¹⁸ meters. To convert, multiply by the conversion factor:

attometers = meters × 1 × 10¹⁸
attometers = meters ÷ 1 × 10⁻¹⁸

Example: convert 1 m to am: 1 × 1 × 10¹⁸ = 1 × 10¹⁸ am.

About the meter

The meter is the SI base unit of length. Since 1983 it has been defined as the distance light travels in a vacuum in 1/299,792,458 of a second. It's used for everyday measurement almost everywhere in the world.

Symbol: m · 1 m = 1 m · Category: Metric (SI)

About the attometer

An attometer is 10⁻¹⁸ meters. It's used in particle physics, for example as an upper bound on the size of quarks and electrons.

Symbol: am · 1 am = 1 × 10⁻¹⁸ m · Category: Metric (SI)
