How to Convert Degrees to Gradians (° to gon)

Updated 5 Oct 2026 in Unit Converters

Angle conversions show up in maths and physics lessons, surveying and navigation. This guide shows how to convert degrees into gradians by hand, with examples and a quick-reference table.

The conversion

To convert degrees to gradians, multiply the value by 1.1111111111. To go the other way, divide by the same number (or multiply by 0.9). For a quick estimate, multiply by about 1.1.

Gradians = degrees × 1.1111111111

Mistakes to avoid

Dropping the units

A bare number without a unit is easy to misread later. Always write the unit with the result.

Forgetting squared and cubed units

Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.

Mixing similar-sounding units

US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.

Background

Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.

Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.

Singapore adopted the metric system in the 1970s, replacing imperial units and traditional Chinese measures in most official uses. Metric units are now standard in schools, trade and government, but older units survive in property, markets and imported goods.
