### Temperature Conversion

The temperature is one of the fundamental metric in the International System of Units (SI), which is a physical property of matter. The basic unit of temperature in the SI is the Kelvin (symbol "K"). Generally, temperature is measured with thermometers, which may be calibrated to a variety of temperature scales. For everyday applications, it usually uses the unit of Celsius scale. Temperature is really important, especially in all fields of natural science.

What are the differences between temperature and heat?
2. Gulshan Jan 17, 2016 at 22:53 pm
Temperature: The metric used to measure the heat content, but it is not energy itself. Its SI unit is kelvin. temperature is measured in Kelvin or Fahrenheit or degrees Celsius. our average body is 37 degrees celsius.

Heat: Energy that is responsible for microscopic rapid motion of molecules. Its SI unit is joule.

Hi Gulshan. What is the SI unit of temperature?
4. Gulshan Jun 19, 2015 at 08:11 am
SI unit of Temperature is Kelvin.

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15, that conversion formula:

T(K) = T(°C) + 273.15

So melting point of ice is 0°C++ 273.15 = 273K and boiling point of water is 100°C+ 273.15 = 373 K.

What is the difference between celsius and fahrenheit?
6. Gulshan Mar 11, 2015 at 07:56 am
Hi Marsh, There are two different units for measuring temperature. Most countries use degrees Celsius, the United States is the only major country that still uses Fahrenheit. Temperature is most commonly expressed using the Celsius or Kelvin scale in the European Union (EU).

How to Calculate:

Fahrenheit to Celsius : °C = (°F - 32) / 1.8

Celsius to Fahrenheit : °F = ℃ × 1.8 + 32

What is the Fahrenheit equivalent of 40 degrees celsius?
8. Gulshan Mar 04, 2015 at 07:21 am
Conversion Formula: T (°F) = T (°C) × 9/5 + 32

now , (40°C × 9/5) + 32 = 104°F
