It will be 20 degree centigrade after 4 hours.
It's chilly, but still above the freezing point of water (i.e. above 32 degrees Fahrenheit).
Four degrees centigrade is the recommended temp for a fridge.
As a general rule of thumb for most substances as the temperature increases the density decreases. There are a few well-known exceptions to the rule; for example the density of liquid water between 0 degrees and four degrees Celsius actually increases with temperature to a maximum at 4 degrees (after which it starts decreasing again). Even more widely known is that liquid water at 0 degrees Celsius is more dense than ice at the same temperature; this is very unusual, as for most substances the solid phase is more dense than the liquid phase.

one thousand four hundred degrees Fahrenheit or 1,400 degrees F.
Four degrees Celsius. Subtracting six from two degrees Celsius gives four degrees Celsius.
44 degrees Celsius is 111.2 degrees Fahrenheit, if you were looking for a conversion.
24 degrees Celsius = 75.2 degrees Fahrenheit
Simple. Just add 273.15 to degrees Celsius to get Kelvin: Four degrees celsius is 277.15 Kelvin (4 + 273.15 = 277.15)
Assuming that degrese is you fail at spelling degreese and that celceus is a fail for Celsius, 6 degrees less than 2 degrees Celsius is four degrees Celsius below zero.

Since you're working with the same units of measurement for all of your readings, you can just place them on a number line. -7 < -5 < 0 < 2 -7C is the coldest of these four.
refrigerator : five degrees Celsius four fridge: minus five degrees Celsius minus 18
There are two reasons for this. The first is that a Fahrenheit degree is smaller than a Celsius degree. Four Celsius degrees is the same size as nine Fahrenheit degrees. The second reason is that 32 degrees Fahrenheit is zero degrees Celsius. If you put those two ideas together you figure out that -40°F = -40°C.
Minus four degrees Celsius would typically be considered cold, as it is below the freezing point of water. Temperature perceptions can vary depending on an individual's tolerance and acclimatization.
Kelvin is the SI unit for temperature. Celsius is usually used in metric systems. 0 degree celsius is 273.15 Kelvin. Kelvin increases equally with celsius. So to convert celsius to kelvin, we just add 273.15 to celsius. The answer in Kelvin is 277.15
Yes, negative four degrees is too cold for a fridge because things will freeze. A fridge should be in the range of one to four degrees C, or 35 to 40 degrees F.
