Answer key: Celsius to Fahrenheit worksheet

1. In Celsius: -6.67 °C
1. Convert to Celsius: subtract 32, then multiply by 5/9
  $(20 °F - 32) \times \frac{5}{9}$ $= −6.6666666667 °C$
2. For a quick check in your head, subtract 30, then halve
  $\frac{(20 - 30)}{2}$ $= −5$
2. In Fahrenheit: 71.6 °F
1. Convert to Fahrenheit: multiply by 9/5, then add 32
  $22 °C \times \frac{9}{5} + 32$ $= 71.6 °F$
2. For a quick check in your head, double it, then add 30
  $22 \times 2 + 30$ $= 74$
3. In Fahrenheit: 62.6 °F
1. Convert to Fahrenheit: multiply by 9/5, then add 32
  $17 °C \times \frac{9}{5} + 32$ $= 62.6 °F$
2. For a quick check in your head, double it, then add 30
  $17 \times 2 + 30$ $= 64$
4. In Fahrenheit: 60.8 °F
1. Convert to Fahrenheit: multiply by 9/5, then add 32
  $16 °C \times \frac{9}{5} + 32$ $= 60.8 °F$
2. For a quick check in your head, double it, then add 30
  $16 \times 2 + 30$ $= 62$
5. In Fahrenheit: 57.2 °F
1. Convert to Fahrenheit: multiply by 9/5, then add 32
  $14 °C \times \frac{9}{5} + 32$ $= 57.2 °F$
2. For a quick check in your head, double it, then add 30
  $14 \times 2 + 30$ $= 58$
6. In Celsius: -7.78 °C
1. Convert to Celsius: subtract 32, then multiply by 5/9
  $(18 °F - 32) \times \frac{5}{9}$ $= −7.7777777778 °C$
2. For a quick check in your head, subtract 30, then halve
  $\frac{(18 - 30)}{2}$ $= −6$
7. In Fahrenheit: 64.4 °F
1. Convert to Fahrenheit: multiply by 9/5, then add 32
  $18 °C \times \frac{9}{5} + 32$ $= 64.4 °F$
2. For a quick check in your head, double it, then add 30
  $18 \times 2 + 30$ $= 66$
8. In Fahrenheit: 75.2 °F
1. Convert to Fahrenheit: multiply by 9/5, then add 32
  $24 °C \times \frac{9}{5} + 32$ $= 75.2 °F$
2. For a quick check in your head, double it, then add 30
  $24 \times 2 + 30$ $= 78$
9. In Celsius: -2.22 °C
1. Convert to Celsius: subtract 32, then multiply by 5/9
  $(28 °F - 32) \times \frac{5}{9}$ $= −2.2222222222 °C$
2. For a quick check in your head, subtract 30, then halve
  $\frac{(28 - 30)}{2}$ $= −1$
10. In Fahrenheit: 78.8 °F
1. Convert to Fahrenheit: multiply by 9/5, then add 32
  $26 °C \times \frac{9}{5} + 32$ $= 78.8 °F$
2. For a quick check in your head, double it, then add 30
  $26 \times 2 + 30$ $= 82$
