How it works
- Converted estimate = × Conversion factor
- Royal cubit ≈ 0.523 m; Common cubit (6 palms) = 6/7 × Royal cubit
- Egyptian palm = Royal cubit/7; Egyptian digit = Royal cubit/28
- Worked example: Under the selected 523 mm royal-cubit reference, two royal cubits span approximately 1.046 metres. A common cubit uses six sevenths of this royal-cubit profile.
- 2 × 0.523 ≈ 1.046 m.

Assumptions and limitations
Approximate historical reference. SI arithmetic does not make reconstructed ancient dimensions exact; use the named profile and its sources.
