Unit family

角度

Degrees and radians are often mixed in software, geometry and trigonometry. Formulas usually expect a specific angle unit.

Factor origin

Factors come from the stored source family and are not derived from rounded display values.

Rounding rule

UnitCloud keeps calculating with stored factors and rounds only the displayed output by selected precision.

When not to use

Do not use as the sole basis for official, medical, safety-critical or contractual decisions.

Common questions

Which base unit does 角度 use?

UnitCloud normalises this family through rad. That keeps tables, direct conversions and batch output consistent.

What is the most common mistake for 角度?

Degrees and radians are often mixed in software, geometry and trigonometry. Formulas usually expect a specific angle unit.

How does UnitCloud round?

UnitCloud keeps calculating with stored factors and rounds only the displayed output by selected precision.
