30 Degrees Fahrenheit to Celsius

Conversion of 30 degrees Fahrenheit to degrees Celsius involves two common temperature scales.

-1.111 degrees Celsius(°C)

Conversion of 30 degrees Fahrenheit to degrees Celsius involves two common temperature scales. Although they all measure temperature, they start at different numbers and rise gradually at different rates. The freezing and boiling points of water are exactly 180 degrees apart on the Fahrenheit scale. It means that 1°F is equivalent to 1/180 of the interval between the freezing and boiling points of water.

The unit size on the Celsius scale is 100 degrees apart on the freezing and boiling points of water. Therefore, one degree Celsius is equivalent to 1/100 of the interval between the two points. When the Fahrenheit scale gives a temperature reading of 30°F the conversion on the Celsius scale will be -1.111°C. Degrees Celsius is an SI derived unit that is used in most countries worldwide. The Fahrenheit scale also serves a similar purpose but is mostly used in the United States.

To determine the conversion from degrees Celsius to degrees Fahrenheit;

100/180 can be simplified as 5/9 or shown in decimals as 0.566.

To get the temperature in degrees Celsius, we first subtract 32 from the temperature in degrees Fahrenheit. The result is then multiplied by 5/9.

Fahrenheit to Celsius Converter


30 °F = -1.111 °C

30 degrees Fahrenheit(°F) = -1.111 degrees Celsius(°C)

Formula

30°F = -1.111°C is the standard principle used in the conversion. Therefore, 30 degrees Fahrenheit is equal to -1.111 degrees Celsius.

T (°C) = [T (°F) – 32] x 5/9 is the method for converting 30 degrees Fahrenheit to degrees Celsius.

For example;

Convert 30 degrees Fahrenheit to degrees Celsius.

Solution

T (°C) = [30°F – 32] X 5/9

= -1.111° Celsius

Other methods that work

We first add 40 to the temperature in degrees Fahrenheit. You will then multiply the result by 5/9 before subtracting from 40 to get the reading in degrees Celsius.

Using the above example;

30 + 40 = 70

70 x 5/9 = 38.89

38.80 – 40 = -1.111° Celsius
