Change between Celsius and Fahrenheit. Every version has 10 questions, and the answer key prints on the second page.

I can use F = 9/5 × C + 32 and C = 5/9 × (F − 32), including below freezing.
I can solve the formula for the other scale by undoing its steps.
I can use reference points: 0 °C = 32 °F, 100 °C = 212 °F and about 37 °C = 98.6 °F.
I can convert a change in temperature (no + 32) and find where the scales meet (−40°).

Standard: IXL parity (Nov 11)

Celsius: The scale where water freezes at 0° and boils at 100°

Fahrenheit: The scale where water freezes at 32° and boils at 212°

formula: A rule written with letters, like F = 9/5 × C + 32

reference point: A known temperature used to check

change in temperature: How much it rises or falls

Your child multiplied by 9/5 but didn't add 32. Fahrenheit starts at 32 where Celsius starts at 0, so add 32.

Your child multiplied first and subtracted 32 last. Take 32 away from the Fahrenheit reading first, then multiply by 5/9.

Your child added 32 to a change in temperature. A change has no starting point, so only multiply by 9/5.

What is the most common mistake with change between celsius and fahrenheit?

Your child multiplied by 9/5 but didn't add 32. Fahrenheit starts at 32 where Celsius starts at 0, so add 32.
