The US is one of the few countries where the temperature measurements are in Fahrenheit. Elsewhere, Celsius is the norm. Usually, when traveling, I want an approximate mapping. Thankfully, it is linear and easy to memorize.
To convert temperature in ºC to ºF - double and add 30 To convert temperature in ºF to ºC - subtract 30 and half
Both of these are approximations for fast calculation
| ºC | ºF |
|---|---|
| 0 | 30 |
| 10 | 50 |
| 20 | 70 |
| 30 | 90 |
| 40 | 105 |
| 50 | 120 |
The mapping is slightly inaccurate for ease of memorization.
