There are no units for measuring the use of temperature.
a protractor
You always use square units when measuring area.
A complete rotation of a ray around a point is 360 degrees or pi radians. That defines the two common units of measuring angles. The measurement of an angle is the number of such units between the two rays which form the angle.
When the angle you are measuring is obviously an obtuse angle (angle above 90 degrees, or when you draw a box in the angle and it turns out bigger than it's supposed to) you use the big numbers. When the angle is obviously acute (opposite definition of obtuse), you use the little numbers.
In geometry angles are measured in degrees.

No, unless you are asked to provide the answer in certain units.

There are special angle-measuring instruments which you can use to measure the angle.

Liters.
Degrees: 0 to 360 Radians: 0 to 2*PI Grads: 0 to 400

Angles are measured using a protractor
We would typically use a sextant to measure the angle of a star above the horizon.
