You know that moment when it’s time to cook, but the recipe you want to make provides temperature information that you’re unfamiliar with? Don’t worry, when you don’t have a calculator on hand, there are other ways how to convert Celsius to Fahrenheit.
What’s the difference between Celsius and Fahrenheit?
Celsius and Fahrenheit are two measurements of temperature. Key differences between the two are that the boiling point of water is 212 degrees Fahrenheit and 100 degrees Celsius and that the freezing point of water is at 32 degrees Fahrenheit and 0 degrees Celsius.
Why do some recipes use Celsius and others Fahrenheit?
Recipes either appear in Celsius and/or Fahrenheit due to their country of origin’s use of the metric system (as Europe does) or imperial units (as the United States does). All countries in the world except for the United States, Myanmar and Liberia use the metric system.
What are some ways to convert Celsius to Fahrenheit without a calculator?
Without a calculator, there are many means to convert Celsius to Fahrenheit.
1. By Hand
Multiply the Celsius temperature by 1.8 and add 32 to get the Fahrenheit conversion With this method you get the exact temperature conversion degree.
Example: What is the temperature in Fahrenheit from 10 degrees celsius?
(10*C x 9/5) + 32= *F
(10*C x 1.8) + 32= *F
(18) + 32 = *F
50= F
You find that 10 degrees Celsius is equal to 50 degrees Fahrenheit.
2. Visual Conversion
Use an infographic chart to visually convert Celsius to Fahrenheit. With this method, there are no mathematic calculations necessary.
3. Unconventional Mathematics Formula
Multiply the Celsius degree by 2, subtract by the first digit of the Celsius temperature then add 32. It’s a unconventional method but simpler in comparison to using the value 1.8 by hand. Please note that using this method may require subtracting a degree or two for a complete accurate conversion.
Example: What is the temperature of Fahrenheit from 10 degrees Celsius?
((10*C x 2) – 1 ) + 32 = ?F
((20)-1)) + 32 = ?F
19 + 32 =?F
51=?F
You find that 10 degrees Celsius is roughly equal to 51 degrees Fahrenheit.
4. Reference Recipes with Similar Conversions
Consult other recipes that contain similar temperature units. Recipes often account for differences in temperature units, so they list the degrees in Fahrenheit and Celsius, which provides a method that’s free of any mathematics.
