As the birthplace of industrial revolution , Britain not only made English the world's first language, but also left many standards for the world. The 1435mm rail track gear pitch that my country's railways have been using is the British standard. There are also two thermometer systems: Fahrenheit (F°) and Celsius (C°), respectively, respectively, and the Fahrenheit temperature is also from the UK. Due to the differences in cultural habits between the East and the West, the two temperature readings often need to be replaced with each other. As long as you remember the following two substitution formulas, it will be easier to swap the two temperatures.
Fahrenheit to Celsius calculation formula: C°= (F°— 32 ) x 5/9 That is, the Fahrenheit temperature is subtracted by 32 first, and then multiplied by 5/9.
Example 1: 98F°— 32 = 66 x 5 = 330 ➗ 9 = 36.7C°
Example 2: 76F° — 32 = 44 x 5 = 220 ➗ 9 = 24.4C°
Celsius to Fahrenheit calculation formula: F° = (C° x 9/5 ) + 32 That is, the temperature of Celsius is first multiplied by 9/5, and then 32.
Example 1: 37C° x 9/5 = 66.6 + 32 = 98.6F°
Example 2: 29C° x 9/5 = 52.2 + 32 = 84.4F°
Primary school mathematics principle: When an integer multiplies with a fraction, multiply by the numerator first, and then divide by the denominator.
