Gradian to Minute Converter
How to Convert Gradian to Minute
1 gradian = 54 minutes
Minute = Gradian × 54
Example: 1 grad × 54 = 54'
Reverse Conversion
To convert minutes back to gradians:
- Remember, 1 minute equals 0.0185185 gradians.
- To convert 54' to grad, multiply
54 x 0.0185185, resulting in1 grad.

Definition of Gradian
- Definition
The gradian (grad) divides a right angle into 100 equal parts, making 400 gradians in a full circle.
It is used in surveying, geodesy, cartography, and some engineering standards, especially in parts of Europe.
- Exact factor
- 1 grad = π/200 rad (exact)
- Examples
- 100 grad = 90°
- 200 grad = 180°
Definition of Minute
- Definition
An arcminute (minute of arc) is 1/60 of a degree.
It is used in astronomy, optics, navigation, geodesy, and surveying for small angular measurements.
- Exact factor
- 1′ = 1/60° = π/10,800 rad (exact)
- Examples
- 60′ = 1°
- 30′ = 0.5°
About the Gradian
Facts & Uses
- 1 gradian (grad, gon) = 1/400 of a full circle = 0.9° exactly. Designed to give a right angle a clean round value of 100 grad.
- Standard in European surveying (especially France, Germany, and parts of Eastern Europe), civil engineering, and topographic mapping.
- Used in some scientific calculators as an alternative angle mode (DEG / RAD / GRAD), though rarely encountered in everyday math.
- Convenient for decimal calculations in surveying because percentages of a quadrant map directly: 50 grad = 45° = half a right angle.
Curiosities
- The gradian was introduced during the French Revolution (1790s) as part of the metric system's push for decimalization — even time was briefly decimalized too.
- The name "gon" (from Greek "gōnía", angle) is the official ISO 31-1 name; "gradian" and "grade" are common synonyms.
- Surveyors who use the gradian point out that a 1% slope = 0.6366 grad — but they prefer the cleaner 1° = 1.111 grad relationship for plan reading.
- Approximate equivalents: 1 grad = 0.9° = π/200 rad ≈ 0.01571 rad; 100 grad = 90° = π/2 rad.

About the Minute
Facts & Uses
- 1 arcminute (′) = 1/60 of a degree = π/10800 rad ≈ 0.000291 rad. NOT to be confused with the time minute.
- Standard for geographic latitude/longitude (1 nautical mile = 1 arcminute of latitude, the original definition).
- Used in astronomy for angular sizes of celestial objects (the full Moon ≈ 31′, Jupiter ≈ 30-50″ depending on opposition).
- Common in marksmanship as MOA (Minutes of Angle) for scope adjustment: 1 MOA ≈ 1 inch at 100 yards (actually 1.047″).
Curiosities
- The arcminute symbol ′ (prime, U+2032) is distinct from the apostrophe ('); using the wrong character is a common typesetting error in scientific writing.
- Human visual acuity: a person with 20/20 vision can distinguish two points separated by about 1 arcminute — the basis of the Snellen eye chart design.
- Geographic coordinates: 40°45′ N reads as "forty degrees, forty-five minutes north" — a precision of about 1.85 km in latitude.
- Approximate equivalents: 1 arcminute = 1/60° = 60 arcseconds ≈ 0.000291 rad.
