Picometer to Femtometer Converter (pm to fm)

How to convert picometers to femtometers

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

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

Example: convert 15 pm to fm: 15 × 1,000 = 15,000 fm.

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)

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)
