Micro:bit acceleration

Hi everyone.
I'm trying to write a code that give the acceleration of X axis and, if it's major than 45° something happens.
Using

Microbit.accel()

I have a string like this

{ "x": 0.115234375, "y": -0.37109375, "z": -0.951171875 }

First of all, what is this measure unit?
How can I get degrees?
And....is there a way to get X, Y and Z separately?

Thanks

It's in g

How can I get degrees?

I believe this should work:

var a = Microbit.accel();
print(Math.atan2(a.x, a.y)*180/Math.PI)

And....is there a way to get X, Y and Z separately?

As above you can save to a variable and access each field separately, or even Microbit.accel().x will work

Thanks Gordon!
I understand.
