Step-by-Step Mathematical Derivation
To convert any quantity from reaumur to r, multiply the quantity by the constant conversion factor 2.25.
To reverse the operation, multiply your r figure by 0.4444444 (or divide by 2.25).
- Identify the starting value in reaumur (°Ré).
- Apply the exact linear conversion factor:
1 °Ré = 2.25 °R. - Multiply the input value by 2.25 to obtain the exact measurement in r (°R).
- Verify precision against standard BIPM / NIST SP 811 statutory guidelines.
