Celcius
Most people use online calculators.
use the formula: celcius to fahrenheit: F=9/5C+32 fahrenheit to celcius: C=5/9(F-32)
Above 100 degree celcius and 343 kelvin
Use the conversion1 cm = 0.3937 inch

To change from one SI prefix to another, we use the conversion factor of 10 raised to the power of the difference between the two prefixes. For example, to convert from centimeters (10^-2) to meters (10^0), we use a conversion factor of 10^2. Simply multiply the value by this conversion factor to make the conversion.
Daniel Fahrenheit invented the scale in 1714 - a mercury in glass thermometer
we need conversion because in one area of world people may use one unit to express the temperature e.g they use kalvin scale but in ur area u use celcius scale to express temperature.u goes to that area where kalvin is used u ask them that what is the temperature now they tell u that it is 44kalvin then u could not understand becoz u underestand only in centigrade then if u know that who a kelvin can b changed in to centigrade u will convert it and easily understand that what temparature is there .as people of different areas use different scales so we need to know these conversions.
Use temperature measurements to measure heat (i.e. Fahrenheit and Celcius)
Use a conversion.
