there's more precision in fahreinheit, why do others keep using celsius?

That's because Celsius uses 0 as the freezing point of water and 100 as the boiling point of water. That makes it easier to use and understand. Same with the rest of the metric system.

Fahrenheit isn't more precise than celcius, it just has smaller intervals between degrees.

32 and 212 are easy enough to understand for me. especially since ive been using them virtually my whole life.

precision is based on the measuring tool, not the scale

Bah rubbish. Boiling water isn't a real metric. Now I have to boil up water and then stick my hand into boiling water to get an idea for what 100 grad is like. No thanks. With Fahrenheit, I put my hand into my armpit and BAM, 100 degrees Fahrenheit.

F is no more "precise" than C. You can use either to whatever precision you want. C seems in inherently easier to use with easy to understand reference points. 0 = freeze. 100 = boil. (at least for water).

I know the boiling and freezing point in C.
what i'm saying it's not applicable in everyday use, namely describing the weather.

Celsius is NEAR 0 for freezing water (even in ideal lab conditions, it isn't exactly 0°C), and is rarely at 100 for boiling water (it is often several degress off due to air pressure variations). And the temperature for both depends a lot on the number of nucleation points available (water will stay liquid far below 0°C if there are no nucleation points). Plus using water for your calibration is arbitrary anyways. Why not ethanol or any other common chemical?

Fahrenheit at least has the advantages of:
1: being weather related (most of the world is between 0°F and 100°F and extremes on either side of that range are a health hazzard).
2: being nicely tuned to heath. A temperature above 100°F is a fever. Why would you want to memorize 38°C when 100°F is easier? Note: using human health is just as arbitrary as using water.
3: matching the precision of human feeling. We can tell the difference between temperatures that are roughly 1°F apart. A 1°F change in the outside temperature or the thermostat is just enough to notice. Like the OP said, 1°C is just too coarse of a temperature range and you are forced to go with decimals.

But, in the end both suck. Neither have an absolute zero at 0. Rankine is the best of all worlds. A true zero and temperature intervals that match human touch.

This and most of the formula we use in chemistry requires us to use kelvins, which are very close to Celsius.

I'd rather use a system based off of something meaningful, rather than a system based off the freezing point of a compound (salt water), and the body temp of some quack with a fever.

Seriously, it's not hard to remember how to spell if you just make it fah-rein-heit.

The creaters of Celsius should have picked something a bit more constant than the boiling point of water for their high number.
