Unit Conversion Formulas
The following formulas are essential for converting between temperature and viscosity units.
Temperature Conversion
The relationship between Celsius () and Fahrenheit () is:
Viscosity Unit Conversions
- Reyn to Pascal-second: 1 reyn (lb_f·s/in²) = 6896.55 Pa·s
- Centistoke to Centipoise: 1 cSt = 1 cP / SG, where SG is the specific gravity of the oil.
