Temperature Conversion Worksheets — °C, K & °F (Free)

Temperature is the one conversion with three common scales. These worksheets practice all three pairs — °C to K (add 273.15), °C to °F (×9/5+32) and °F to °C — with exact constants. They pair naturally with the UnitFig temperature converters so students can verify any answer.

Teaching tips for temperature

  • •Celsius → Kelvin: add 273.15 (K = °C + 273.15). Zero Kelvin is absolute zero.
  • •Celsius → Fahrenheit: °F = °C × 9/5 + 32. The ×9/5 step is the scale stretch; +32 shifts the zero point.
  • •Anchor points: 0 °C = 32 °F = 273.15 K (water freezes); 100 °C = 212 °F = 373.15 K (water boils). Use them to sanity-check.

Common mistakes to watch for

✗ Forgetting to add 32 in °C → °F.
✓ The +32 shifts the zero point; without it 0 °C would wrongly map to 0 °F. Always do ×9/5 first, then +32.
✗ Subtracting 273.15 the wrong way for K → °C.
✓ °C = K − 273.15. Since K is always larger than the °C number, you subtract to get back to Celsius.

Grade & standards alignment

These temperature worksheets target the Grades 6–10 band of the Common Core State Standards for Mathematics (CCSSM). The relevant CCSS math domains are:

Physical Science — Matter & Thermodynamics

The CCSSM are public, open-license standards; this alignment is provided for planning and is not an official endorsement by the standards authors.

How these worksheets are built (accuracy & trust)

  • •Problems are generated by a deterministic engine using exact integer and rational arithmetic — answers are reduced to lowest terms and never rely on floating-point rounding, so they match the matching UnitFig converter.
  • •Grade presets follow the CCSSM progression above; pick a grade to get age-appropriate number ranges.
  • •Content is reviewed for accuracy and refreshed each year (2026). Worksheet copy and examples are original and written for classroom use.

Safe for classrooms — zero data collection

UnitFig collects no personal information from children or any visitor. Worksheets run entirely in the browser: no account, no name or email, and student answers never leave the device. We follow a COPPA-aligned, zero-collection design so teachers and parents can use these sheets without a signup wall or privacy concern. See our Privacy Policy.

Frequently Asked Questions

What is the formula for Celsius to Kelvin?

K = °C + 273.15. The worksheet engine applies this exact constant, matching the UnitFig temperature converters.

Why does °F use 9/5 and 32?

9/5 stretches the Celsius degree to the Fahrenheit degree (180°F span vs 100°C span per 100 degrees), and +32 aligns the zero points (water freezes at 0 °C / 32 °F).

What grade covers temperature scales?

Typically grade 6–10 physical science, as part of matter and thermodynamics.
