20 degrees Fahrenheit = -6.6 degrees Celsius.
20 deg Celsius = 20 + 273.15 = 293.15 K
20 degrees Celsius = 68 degrees Fahrenheit Formula: [°F] = [°C] × 1.8 + 32

It can be a conversion factor - though not necessarily. For example, 68 deg Fahrenheit = 20 deg Celsius. But there is no conversion factor for F-to-C: instead there is a linear equation.
Water at 40 degrees Celsius will have a greater density compared to water at -20 degrees Celsius. This is because water density decreases as temperature increases up to 4 degrees Celsius, and then increases beyond that point. At 40 degrees Celsius, water is in its most dense state before it starts to decrease in density as it gets closer to boiling temperature.
20 degrees Fahrenheit = -6.6 degrees Celsius.
20 deg Celsius = 20 + 273.15 = 293.15 K
It is 20 deg Celsius.
68 deg F = 20 deg C
There IS a difference, which arises because the Celsius scale is not an absolute scale: its zero is arbitrary. What this means is that 20 deg C is not twice as warm as 10 deg C. So, the difference between 10 deg C and 20 deg C is NOT 10 deg C but 10 Celsius degrees.In other words, one Celsius degree is the difference in temperature between n deg C and (n+1) deg C (for any n > -273) whereas one degree Celsius is a specific temperature - a bit above the freezing point of pure water under normal pressure.
It just remains as water. The freezing point of water is 0 degrees Celsius, while the freezing point is 100 degrees Celsius. Therefore at 20 degrees Celsius, there is no change in state and it just remains as water.
Below zero Celsius refers to temperatures that are below the freezing point of water (0 degrees Celsius). Negative 20 Celsius is a specific temperature that is 20 degrees below zero on the Celsius scale. Both temperatures indicate cold weather conditions.
Energy change to convert 1.5 kg of water at 20 deg C to water at 0 deg C:q = smT = 4.184 x 1.5.x 20 = 125.52 kJEnergy change when 1.5 kg of water at 0 deg C is converted to ice at 0 deg C:q = L x m ( where L is the latent heat per kg) = 334 x 1.5 = 501 kJTotal = 125.52 + 501 = 626.52 kJ
20 below zero degrees Fahrenheit is equal to approximately -28.9 degrees Celsius.
Minus 4 degrees Fahrenheit is equal to approximately -20 degrees Celsius. This can be calculated using the formula: (Fahrenheit temperature - 32) x 5/9 = Celsius temperature.
20 degrees Celsius = 68 degrees Fahrenheit Formula: [°F] = [°C] × 1.8 + 32
