In this article, we are going to learn the conversion of Celsius to Fahrenheit by using javascript. by using the formula: Fahrenheit = (Celsius * 9/5) + 32.
Fahrenheit
Fahrenheit is a scale of temperature. Its unit is the degree Fahrenheit (°F). This unit is named after physicist Daniel Gabriel Fahrenheit who first proposed this temperature scale in 1724. On the Fahrenheit scale, the water freezes at 32°F and boils at 212°F under normal conditions. Fahrenheit is also the U.S. customary measurement unit of temperature.
Celsius
Celsius is also a scale of temperature. Its unit is the degree Celsius (°C). This unit was named after astronomer Anders Celsius in 1948. On the Celsius scale, the water freezes at 0°C and boils at 100°C under normal conditions. Almost the whole world uses Celsius for temperature measurement aside from the U.S. Celsius is sometimes referred to as Centigrade.
The formula for converting the Celsius Scale to the Fahrenheit Scale is:
T(°F) = T(°C) × 9/5 + 32
Example
Convert 10 degrees Celsius to degrees Fahrenheit:
T(°F) = 10°C × 9/5 + 32 = 50°F
There are several methods that can be used to Convert Celsius to Fahrenheit by using the above-mentioned formula, which are listed below:
- Using the formula: Fahrenheit = (Celsius * 9/5) + 32, with custom function
- Using the arrow function and template literals
We will explore all the above methods along with their basic implementation with the help of examples.
Approach 1: Using the formula: Fahrenheit = (Celsius * 9/5) + 32, with custom function
In this approach, we are using a javascript custom function and applying the formula: Fahrenheit = (Celsius * 9/5) + 32. For a given temperature of 20°C.
Syntax:
function celcToFahr( n ) {
return ((n * 9.0 / 5.0) + 32.0);
}
Example: In this example, we are using the above-mentioned approach.
Javascript
// Javascript Program to convert Temperature // from Celsius to Fahrenheit // function to convert Celsius // to Fahrenheit function celcToFahr( n ) { return ((n * 9.0 / 5.0) + 32.0); } // Driver code const n = 20; console.log(celcToFahr( n )); |
68
Approach 2: Using the arrow function and template literals
In this approach, we are using the arrow function and template literals to convert Celsius to Fahrenheit. The arrow function applies the formula: Fahrenheit = (Celsius * 9/5) + 32. For a given temperature of 20°C.
Syntax:
const celcToFahr = (n) => `${n} Celsius is equal to ${(n * 9 / 5) + 32} Fahrenheit.`;
Example: In this example, we are using the arrow function with the formula: Fahrenheit = (Celsius * 9/5) + 32.
Javascript
const celcToFahr = (n) => `${n} Celsius is equal to ${(n * 9 / 5) + 32} Fahrenheit.`; const n = 20; console.log(celcToFahr(n)); |
20 Celsius is equal to 68 Fahrenheit.
