- Confusing colatitude with longitude.
- Using it as a synonym for 'co-latitude' in a non-technical sense (e.g., sharing a similar latitude).
FAQ
Frequently Asked Questions
Latitude is measured from the equator (0°) to the poles (±90°). Colatitude is its complement, measured from the zenith (the point directly overhead, 0°) to the horizon (90°), so colatitude = 90° - latitude.
No, it is an exclusively technical term used in scientific disciplines like astronomy, geodesy, and physics.
No, by definition, colatitude ranges from 0° (at the zenith) to 180° (at the nadir), but in common usage for points on or above the Earth's surface, it typically ranges from 0° to 90°.
The most direct synonym is 'zenith distance', which describes the same angular measurement from the observer's zenith.
In astronomy and geometry, the angular distance from the zenith to a point on the celestial sphere.
Colatitude is usually technical in register.
