Because it is measured in even numbers with a 0 degree freezing point and a 100 degree boil.
Either - it all depends what you learnt when growing up, or have adapted to as you've grown older. The Fahrenheit scale is almost twice the size of the Celsius scale (between freezing and boiling on Celsius there are 100 degrees, but on the Fahrenheit there are 180 degrees) meaning that smaller temperature differences show up as a larger difference with the Fahrenheit scale than with the Celsius scale. They are just as easy as each other, though scientists prefer Kelvin which has the same unit differences as Celsius but starting with 0 K = -273.15oC (water freezes at 273.15 K and boils at 373.15 K). The Fahrenheit scale was originally intended to be 0oF = freezing point of brine, nominally 32oF = freezing point of water and 96oF = normal body temperature, but later scientists redefined the scale slightly so that water did freezer at exactly 32o F which made body temperature 98.4oF.
160 Celsius = 320 Fahrenheit
The Celsius scale has its 'zero' at the same temperature as 32 on the Fahrenheit scale, and each Celsius degree is the same size as 1.8 Fahrenheit degrees.
68 degree celsius = 154.4 Fahrenheit
65 degrees Fahrenheit is 18.3 degrees Celsius.
Celsius, kelvin, Fahrenheit
The scientists who were behind the temperature measurements scale were quite a number. Galileo Galilei invented the water thermoscope, Daniel Gabriel Fahrenheit was responsible for the Fahrenheit scale, Kelvin scale was invented by Lord Kelvin and Anders Celsius invented the Celsius scale.
The Kelvin scale is an absolute scale. This means that at 10 K there is twice as much thermodynamic activity as there is at 5 K. This property does not apply to either the Celsius or Fahrenheit scale - where the zero is arbitrary. A difference of 1 Kelvin is the same as a difference of 1 Celsius degree which is why, as an alternative scale, Celsius is preferred to Fahrenheit.
The units, in this case, are kelvin, degrees Fahrenheit, and degrees Celsius.

50 celsius Hotter on Celsius Scale
−273.15° on the Celsius scale which equates to −459.67° on the Fahrenheit scale

The C is Celsius and the F is Fahrenheit. On a Celsius scale water freezes at 0 degrees Celsius and boils at 100 degrees Celsius. On a Fahrenheit scale water freezes at 32 degrees Fahrenheit and boils at 212 degrees Fahrenheit because Celsius is used world wide and Fahrenheit is used only in the U.S.
23 degrees Celsius is a temperature reading on the the Celsius scale. To compare to the Fahrenheit scale 23 degrees Celsius is equal to 73.4 degrees Fahrenheit.
The Celsius scale has its 'zero' at the same temperature as 32 on the Fahrenheit scale, and each Celsius degree is the same size as 1.8 Fahrenheit degrees.
