What is a Degree?

A degree is a widely used unit of angle defined as 1/360 of a full rotation. It's the most common angular unit in geometry, navigation, and daily use.

What is a Radian?

A radian is the standard SI unit of angular measure, defined as the angle formed when the arc length equals the radius. One full rotation is 2π radians.

Conversion Formula

To convert Degree to Radian, use the formula:

Radian = Degree × (1.7453292520e-2 / 1.0000000000e+0)

This formula works by converting Degree into radians as the base unit, then converting that result into Radian. It ensures high-precision conversion.

Example: Convert 10 Degree to Radian:
10 × (1.745329e-2 ÷ 1.000000e+0) = 0.1745329252 Radian
