▲ 53 ▼ LPT: Easy way to convert Celsius to Fahrenheit (lemmy.world) submitted 1 year ago by xylogx@lemmy.world to c/lifeprotips@lemmy.world 17 comments fedilink hide all child comments Double the number, then reduce by one-tenth the doubled number, then add 32 Example: To convert 25 C double it to 50, reduce by 5 to get 45, then add 32 to get 77 F. The reason this works is because 9/5 = 10/5 - 1/5. And the nice thing about this is that it is an exact conversion not an estimation.
