How fo I change the degrees from C to F degree ?

A Celsius degree is larger than a Fahrenheit degree by 80%. But, Celsius sets its zero point at the freezing point of water, which is 32 degrees Fahrenheit. So The conversion always includes adding 32 when going from Celsius to Fahrenheit and subtracting 32 when going the other direction. So the two formulas are as follows: Degrees F = Degrees C times 1.8 plus 32.
Degrees Celsius = (Degrees F minus 32) times 0.5556

Now, keeping it straight as to when to add or subtract 32 is also easy. Always do it while in degrees F. So, if you are going from degrees F to Celsius, subtract that 32 first because you are sill in F sized degrees. Conversely, when going from degrees C to F, wait until you've done the multiplication to convert your degrees to F, and then add the 32. Those 32 degrees in the differential are F degrees, not C degrees.

Finally, it may be easier to remember just the 1.8 or 180% instead of that 0.5556. That's ok. Just whip out your calculator and divide 1 by 1.8, which in math is called taking the reciprocal.

C = [(F - 32) * 5] / 9

Pressing the - (minus) button on the back toggles temperature units. Pressing + (plus) toggles barometric pressure units.

1 degree C = 1.8 degree F.
0 degree C = 32 degree F.
100 degree C = 212 degree F.

things that need checking:
refrigerant level. Super heat. Condenser clean? Compressor effeciency.
These are things that an experienced tech can check. If you have some experience and gages/ tools, I can give you some things to do but most of this requires experience.
Let me know if I can be of any further help.

If the engine turns over but does not start the first thing to check would be fuel pump, and or fuel injectors.

You can keep using that oil with no problems. Most people don't really understand what the numbers on the bottle actually mean. There is a really long definition but here is the short version: The first number represents the pour point of the oil at freezing (@32 degrees F).
The second number represents the protection offered, compared to a "straight weight" oil eg: 30, 40, 50, at 212F degrees. Therefore, at freezing, your oil will pour (or flow) like a 20 weight oil, and give wear protection of a 50 weight oil at 212 degrees.
The quality of any oil is based upon the chemical makeup of the base oil, some have a high parafin content and are prone fo sludge formation, while better ones do not and tend to last longer. The ability to "change weights" with temperature is controlled by an additive "package" which is part of the product formula, as are other features such as anti foaming and the ability to keep particles in suspension.
If you stay with better oils such as Castrol, Quaker State, Valvoline etc. You will have no problems. (especially because in your area you don't go from sub zero to 100's).
Don't forget to add a quality filter to your oil changes. This is as important as your oil!!!
Good luck with your car!!!

Its raked out at 32 degrees

This range has a 30 degree drp before it reheats. Change the thermostat rread the instructions. All for free
