LET’S WORK IT OUT
Your numbers, your answer.
THE WHY BEHIND THE ANSWER
How it works.
Temperature scales have different zero points as well as different unit sizes. Convert through Celsius to account for both.
THE FORMULA°F = °C × 9/5 + 32; K = °C + 273.15
Worked example
25 °C × 9/5 + 32 = 77 °F.
Good to know
Values below absolute zero are rejected. Kelvin is written without the degree sign.
