How to convert megameters to picometers

1 megameter is equal to 1 × 10¹⁸ picometers, and 1 picometer is equal to 1 × 10⁻¹⁸ megameters. To convert, multiply by the conversion factor:

picometers = megameters × 1 × 10¹⁸
picometers = megameters ÷ 1 × 10⁻¹⁸

Example: convert 1 Mm to pm: 1 × 1 × 10¹⁸ = 1 × 10¹⁸ pm.

About the megameter

A megameter is one million meters (1,000 km). Earth's radius is about 6.4 Mm.

Symbol: Mm · 1 Mm = 1,000,000 m · Category: Metric (SI)

About the picometer

A picometer is 10⁻¹² meters. It's used for atomic and ionic radii and bond lengths; a hydrogen atom is about 50 pm across.

Symbol: pm · 1 pm = 1 × 10⁻¹² m · Category: Metric (SI)

Frequently asked questions
