deg to grad calculator

Angles are measured in various units, including degrees, radians, and gradians. While degrees are commonly used in everyday applications, gradians are popular in surveying, engineering, and construction because they simplify certain calculations.

What is a Degree?

A degree (°) is a standard unit of angle measurement.

  • 1 full circle = 360°
  • Degrees are widely used in geometry, navigation, construction, and general mathematics.

What is a Gradian?

A gradian (also called gon or grade) is a unit of angle measurement where a full circle is divided into 400 gradians.

  • 1 full circle = 400 gradians
  • Gradians are commonly used in surveying, civil engineering, and cartography because calculations often involve decimal fractions of 100, which are easier to work with.

Degrees to Gradians Conversion Formula

To convert degrees into gradians, use the formula:

Formula:
gradians = degrees × (400 / 360)

Simplified:
gradians = degrees × 10 / 9


Example Conversions

  1. Convert 90° to gradians
    • gradians = 90 × 10 / 9 = 100 g
  2. Convert 180° to gradians
    • gradians = 180 × 10 / 9 = 200 g
  3. Convert 45° to gradians
    • gradians = 45 × 10 / 9 = 50 g
  4. Convert 360° to gradians
    • gradians = 360 × 10 / 9 = 400 g
  5. Convert 30° to gradians
    • gradians = 30 × 10 / 9 ≈ 33.333 g
