Formula

V_{\text{target}} = (V_{\text{source}} \times F_{\text{mult}}) + F_{\text{offset}}, \quad [M][L]^a [T]^b [\Theta]^c

High-precision IEEE 754 floating-point dimensional analysis across SI, Imperial, US Customary, and CGS unit systems.

Assumptions

  • · Conversion factors referenced from certified NIST/BIPM standard definitions
  • · Temperature offset factors (°C, °F, K, °R) applied after multiplicative scaling
  • · Numerical rounding maintains significant figures per engineering measurement convention
