Convert between Celsius and Kelvin Worksheets - Free Printable

Let’s solve each problem step by step.

We need to convert between Celsius (°C) and Kelvin (K).

The rules are:
- To go from Celsius to Kelvin: add 273.15 → K = °C + 273.15
- To go from Kelvin to Celsius: subtract 273.15 → °C = K - 273.15

But in many school problems, they use 273 instead of 273.15 for simplicity — unless told otherwise, we’ll use 273.

Part A: Convert from Celsius to Kelvin

1) 46 °C → 46 + 273 = 319 K

2) -17 °C → -17 + 273 = 256 K

3) 69 °C → 69 + 273 = 342 K

4) 172 °C → 172 + 273 = 445 K

5) 213 °C → 213 + 273 = 486 K

6) 8 °C → 8 + 273 = 281 K

7) -14 °C → -14 + 273 = 259 K

8) 30 °C → 30 + 273 = 303 K

Part B: Convert from Kelvin to Celsius

1) 301 K → 301 - 273 = 28 °C

2) 259 K → 259 - 273 = -14 °C

3) 268 K → 268 - 273 = -5 °C

4) 364 K → 364 - 273 = 91 °C

5) 467 K → 467 - 273 = 194 °C

6) 432 K → 432 - 273 = 159 °C

7) 324 K → 324 - 273 = 51 °C

8) 350 K → 350 - 273 = 77 °C
