What is a fingerbreadth?

A fingerbreadth is an informal measure of length based on the width of an adult human finger. Its exact value varies but is roughly 1.5 to 2 cm.

What is an attometer [am] used for?

The attometer is used to express extremely small distances relevant in subnuclear physics, high-energy physics, and quantum mechanics.

Can I use fingerbreadths for precise scientific measurements?

No, fingerbreadth is a rough, informal unit and is not suitable where high precision is required.

Browser-based and easy to use with quick input and conversion.

Examples

1 Fingerbreadth equals 19,050,000,000,000,000 attometers.
2 Fingerbreadths equal 38,100,000,000,000,000 attometers.

Common Use Cases

Translating informal human-scale measurements to precise quantum-scale units.
Understanding distances in particle, nuclear, and high-energy physics contexts.
Providing rough measurement conversions for scientific modeling at the subnuclear level.

Tips & Best Practices

Remember that fingerbreadth is an informal unit and varies between individuals.
Use the conversion primarily for theoretical or contextual understanding rather than precise measurement.
Verify scientific measurements through standard instruments when exact precision is needed.

Limitations

Fingerbreadth is a non-standard unit with varying values, limiting exact accuracy.
Attometers are used for lengths far smaller than practical human measurement scales.
Conversions serve mainly as conceptual links between everyday and scientific length scales.
