# Temperature Conversion

Measurement is one of the important terms in our day to day life. Temperature is a measurement of the balance between heat lost and heat produced by the body. Temperature can be measured in the mouth, armpit, rectal or by ear. Temperature is usually measured in terms of Fahrenheit and Celsius. Fahrenheit and Celsius both measure the temperature, but use different numbers, like when we freeze water, it measures $0^0$ in Celsius, but $32^0$ in Fahrenheit.

## Temperature Conversion Formula

Given below are the formulas for temperature conversion.

### Fahrenheit to Celsius Conversion Formula:

To convert Fahrenheit to Celsius, deduct 32 from Fahrenheit temperature, then multiply by 5, then divide by 9.

The formula for converting Fahrenheit to Celsius conversion is given as follows,

Tc = $\frac{5}{9}$ * (Tf - 32)

Where,

Tc = Temperature in Degrees Celsius

Tf = Temperature in Fahrenheit

### Celsius to Fahrenheit Conversion Formula:

To convert Celsius to Fahrenheit, multiply Celsius temperature by 9, then divide by 5, then add 32.

The formula for converting Celsius to Fahrenheit conversion is given as,

Tf = $\frac{9}{5}$ * Tc + 32

Where,

Tc = Temperature in Celsius,

Tf = Temperature in Fahrenheit.

## Temperature Conversion Chart

Temperature conversion table is given as follows:

### Body Temperature Conversion Chart

This chart is helpful to convert Celsius to Fahrenheit for body temperatures. To convert a temperature in Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and multiply that number by $\frac{5}{9}$. To convert a temperature in Celsius to Fahrenheit, multiply by $\frac{9}{5}$ the celsius temperature and then, add 32 to that number.

## Absolute Temperature Conversion

The Kelvin scale is an absolute, thermodynamic temperature scale using as its null point absolute zero. The Kelvin (K) temperature scale uses the same size degree as Celsius. To convert from Celsius to Kelvin, add 273.16 to the Celsius reading.

To calculate a Kelvin temperature, add 273.15 to the Celsius temperature:

tK = tC + 273.15

Absolute zero is defined as a temperature of precisely 0 kelvins, which is equal to -273.15 $^0$C or -459.67 $^0$F.

## Axillary Temperature Conversion

The body temperature that is determined by placing the thermometer under the armpit is known as axillary temperature. The axillary temperature is taken outside the body and the air outside can also affect the reading.

The normal axillary temperature range is anywhere between 96.6 $^0$F and 98.6$^0$F or 36$^0$C and 37$^0$C.

## Rankine Temperature Conversion

Rankine is a absolute temperature scale. The symbol for degrees Rankine is $^0$R. Rankine degree is defined as equal to one degree Fahrenheit. A temperature of -459.67 $^0$F is exactly equal to 0 $^0$R.

### Degrees Temperature Conversion

## Temperature Conversion Problems

Given below are some of the examples on Fahrenheit to Celsius conversion problems.

### Temperature Conversion Fahrenheit to Celsius

Let us convert 68 degree Fahrenheit to degree Celsius.

The formula for converting Fahrenheit to Celsius conversion is,

Tc= $\frac{5}{9}$ * (Tf - 32)

Tc= 68 (Given)

=> Tc= $\frac{5}{9}$ * (68 - 32)

Tc= $\frac{5}{9}$ * 36

Dividing 36 by 9, we get 4.

Tc= 5 * 4

Tc= 20 degree

The answer is 20 degree Celsius.

### Temperature Conversion Celsius to Fahrenheit

Let us convert 50 degree Celsius to degree Fahrenheit.

The formula for converting Celsius to Fahrenheit is given as,

Tf= $\frac{9}{5}$ * Tc+ 32

Tc = 50 (Given)

=> Tf= $\frac{9}{5}$ * 50 + 32

Tf= 9 * 10 + 32

Multiplying 9 and 10, we get 90,

Tf= 90 + 32

Tf= 122 degree Fahrenheit

The answer is 122 degree Fahrenheit.
