How to convert kilometers to attometers
1 kilometer is equal to 1 × 10²¹ attometers, and 1 attometer is equal to 1 × 10⁻²¹ kilometers. To convert, multiply by the conversion factor:
attometers = kilometers × 1 × 10²¹
attometers = kilometers ÷ 1 × 10⁻²¹Example: convert 1 km to am: 1 × 1 × 10²¹ = 1 × 10²¹ am.

About the kilometer
A kilometer is 1,000 meters. It's the standard unit for distances between places, road signs and running races in most countries.
Symbol: km · 1 km = 1,000 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)
