deg F
20 deg C = 68 deg F
Conversion Basis
Temperature affects material properties, water viscosity, density, curing, and environmental measurements. Unlike most engineering unit conversions, temperature scales include offsets as well as scale factors.
deg F = deg C x 9/5 + 32; K = deg C + 273.15
Common Examples
- 20 deg C = 68 deg F
- 32 deg F = 0 deg C
- 0 deg C = 273.15 K
Engineering Use and Limitations
- Temperature differences convert by scale only; an interval of 1 deg C equals an interval of 1.8 deg F.
- Kelvin and Rankine are absolute scales and should not be entered below absolute zero.
- Laboratory standards may specify a reporting or calibration temperature that still governs after conversion.
