Femtometer to Picometer Converter (fm to pm)

How to convert femtometers to picometers

1 femtometer is equal to 0.001 picometers, and 1 picometer is equal to 1,000 femtometers. To convert, multiply by the conversion factor:

picometers = femtometers × 0.001
picometers = femtometers ÷ 1,000

Example: convert 15 fm to pm: 15 × 0.001 = 0.015 pm.

A femtometer is 10⁻¹⁵ meters, the scale of atomic nuclei. A proton has a radius of about 0.84 fm.

Symbol: fm · 1 fm = 1 × 10⁻¹⁵ m · Category: Metric (SI)

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
