How to Convert Arcminutes to Gradians (′ to gon)
Angle conversions show up in maths and physics lessons, surveying and navigation. This guide shows how to convert arcminutes into gradians by hand, with examples and a quick-reference table.
The conversion
To convert arcminutes to gradians, multiply the value by 0.0185185185. To go the other way, divide by the same number (or multiply by 54). For a quick estimate, multiply by about 0.019.
Gradians = arcminutes × 0.0185185185
Worked examples
- 3 ′ = 0.055556 gon
- 12.5 ′ = 0.231481 gon
- 75 ′ = 1.3889 gon

Common questions
Is ′ to gon exact?
The factors used here are the internationally defined values where they exist; results are rounded for display only.

Mistakes to avoid
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
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.
Background
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
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.
