Convert Temperatures
Use the formula matching the source and target scales. Kelvin is an absolute temperature scale.
Formula: C = (F − 32) × 5/9; F = C × 9/5 + 32; K = C + 273.15
Choose the source and target units carefully because the conversion factor depends on the direction of the conversion. A reverse conversion should return the original quantity, apart from rounding.
Verify the result by reversing the conversion with the reciprocal factor; the original value should be recovered apart from rounding.
