Q: What is the cubit (UK)?

The cubit (UK) is a historical unit of length based roughly on the distance from the elbow to the tip of the middle finger, commonly considered about 18 inches or 45.72 cm.

Convert measurements from the historical cubit (UK) unit to the atomic unit of length, the Bohr radius, useful for bridging ancient length scales with atomic physics.

Examples

2 cubits (UK) equals approximately 1.72796544396 × 10¹⁰ atomic units of length.
0.5 cubit (UK) converts to about 4.31991360989 × 10⁹ atomic units of length.

Common Use Cases

Interpreting historical measurements like dimensions in ancient architecture and artifacts.
Translating biblical or historical texts referencing cubits for modern scientific analysis.
Expressing atomic geometries and interatomic distances in quantum chemistry and atomic physics.

Tips & Best Practices

Confirm the historical context when using cubit measurements due to variable lengths over time.
Use this conversion mainly for interdisciplinary or theoretical applications rather than practical engineering.
Carefully interpret large numerical values since atomic units of length are extremely small.

Limitations

Cubit lengths vary by period and location, so exact conversion may differ depending on definition.
Atomic units of length are extremely small, resulting in very large converted numbers that require careful handling.
This conversion is theoretical and not designed for everyday or engineering measurements.
