How to convert -273.15 °C to °F
Use the formula °F = (°C × 9/5) + 32 and substitute -273.15 for °C:
°F = (-273.15 × 9/5) + 32°F = -491.67 + 32°F = -459.67
So -273.15 °C = -459.67 °F.
What does -273.15 °C mean?
This is absolute zero, the lowest temperature physically possible — the point at which particles have the minimum possible thermal energy. It is 0 on the Kelvin scale and −459.67 °F.

The Celsius to Fahrenheit formula
°F = (°C × 9/5) + 32
Multiply the Celsius temperature by 9/5 (1.8) because a Celsius degree is 1.8 times larger than a Fahrenheit degree, then add 32 because water freezes at 32 °F rather than 0 °F. To go the other way, use °C = (°F − 32) × 5/9 — for example, -459.67 °F back to Celsius gives -273.15 °C.
