Degrees, radians, or gradians?

When you’re doing math stuff, in trigonometry, do you prefer using degrees, radians, or gradians?

Radians of course, the natural unit.
I also prefer Kelvin over ºC or ºF.

idk, whatever is the default on whatever calculator I'm permitted.

I use all three and still get the answer wrong rofl

my calculator is set to radians by default, but I primarily use degrees

I personally think the degree system is more intuitive, but the radian system is definitely more convenient for calculations.

Also, Kelvin (the thermodynamic temperature scale) doesn't seem to be all that much more useful than Celsius—they're really easy to convert between!

Radians are actually dimensionless quantities. Angles don't have dimensions, and "radian" just means "1". It's always redundant to say "radian," it's just a way to signify that we are talking about angles. Degrees and gradians also are dimensionless quantities. A degree is another name for the number π/180, and a gradian is π/200.

Do people still use gradians??

I can't find my reading glasses right now but yeah, I also like radishes.
