❓ FAQs

How to convert Celsius to Fahrenheit?▼

Multiply by 9/5 (or 1.8) then add 32. Formula: °F = (°C × 9/5) + 32. Example: 100°C = (100 × 1.8) + 32 = 212°F. Quick trick: double the Celsius, subtract 10%, add 32.

How to convert Fahrenheit to Celsius?▼

Subtract 32 then multiply by 5/9. Formula: °C = (°F - 32) × 5/9. Example: 72°F = (72 - 32) × 5/9 = 22.22°C.

What is Kelvin?▼

Kelvin is the SI unit of temperature. It starts at absolute zero (0 K = -273.15°C), the coldest possible temperature. To convert: K = °C + 273.15. Kelvin doesn't use the degree symbol — it's just "K".

At what temperature are Celsius and Fahrenheit equal?▼

-40! At -40°C = -40°F. This is the only point where both scales intersect. You can verify: (-40 × 9/5) + 32 = -72 + 32 = -40.

What is Rankine scale?▼

Rankine is the absolute temperature scale for Fahrenheit, like Kelvin is for Celsius. 0°R = absolute zero (-459.67°F). Formula: °R = °F + 459.67. Used mainly in US engineering.

What is absolute zero?▼

Absolute zero is the lowest possible temperature: 0 K = -273.15°C = -459.67°F. At this point, atoms have minimal motion. It can never actually be reached but scientists have gotten within billionths of a degree.
