How Do You Estimate Celsius Temperatures In Fahrenheit?
There are many different methods. • The first method: • Take the Celsius temperature and double it. • Add 30 to the result of step 1. • This is the approximate temperature in Fahrenheit. The second method: • Add 40. • Multiply by 5/9 (about 0.56) or 9/5 (1.8), depending on which way you’re going. • Subtract 40. The third method: • Treat every 5 degrees C as 10 degrees F, starting at 0C. • Start with 0C as 30F (we know it’s really 32F, but ignore that for now) • 5C is 40F, 10C is 50F, 15C is 60F, 20C is 70F, 25C is 80F, 30C is 90F, 35C is 100F • Scale becomes less accurate at the ends (i.e. 0C should be 32F, 100F is really 37.8C), but it works more or less for casual estimates when travelling.
