Question 14 • Fall 24 GSE Physical Science B IC

Which shows the formula for converting from kelvins to degrees Celsius?

Answer
°
°C = (9/5 × K) +32
°
°C = 5/9 × (K – 32)
°
°C = K – 273
°
°C = K + 273

Explanation

To convert kelvins to degrees Celsius, subtract 273.15 from the kelvin temperature: °C = K − 273.15. Choice C uses 273 as a rounded approximation, so it is the correct choice. The other formulas apply to Fahrenheit conversions or add kelvins instead of subtracting the offset.
