Convert deg to rad

About ° to rad

This conversion scales values from a smaller angle unit to a larger one. That usually decreases the numeric value when going from ° to rad.

Degree

Definition: Degree (°) is a standardized unit used to measure angle.

History/Origin: This unit is part of established international or regional measurement systems and is included in engineering and scientific references.

Current use: This unit appears in real-world angle calculations, technical documentation, and day-to-day conversions.

Radian

Definition: Radian (rad) is a standardized unit used to measure angle.

History/Origin: This unit is part of established international or regional measurement systems and is included in engineering and scientific references.

Current use: This unit appears in real-world angle calculations, technical documentation, and day-to-day conversions.

How to Convert Degree to Radian

1 ° = 0.0174532925 rad

1 rad = 57.2957795131 °

Formula: value × 0.0174532925199

Example: 15 ° = 0.2617993878 rad

1. Start with the value in Degree (°).
2. Multiply by 0.0174532925 (or divide by 57.2957795131) to get Radian (rad).
3. Use an appropriate decimal precision based on your use case.

Common Use Cases for ° to rad

• Convert ° to rad when sharing angle values across teams that use different unit standards.
• Use this direction in spreadsheets and automation flows where inputs are recorded in ° but reporting is required in rad.
• Apply the ° → rad conversion when validating supplier, lab, or field values against your internal benchmarks.
