Latitude Degrees to Nautical Miles: passage planning, crew briefings, instrument-to-chart unit checks, and verifying mental math when tired or in rough weather.
Tips for accuracy
- Match input units to your chart, GPS, or instrument before trusting the Latitude Degrees to Nautical Miles.
- Cross-check important outputs with a second method or crew when visibility or motion is poor.
- Treat simplified models (waves, radar horizon, etc.) as estimates; real conditions vary.
Practical examples
- 1° lat = 60 nm
- 0.5° = 30 nm
Frequently Asked Questions
Does this work for longitude everywhere?
Only at the equator. Elsewhere use cos(latitude) scaling or a rhumb/great-circle tool.
How accurate is this calculator?
It uses standard maritime formulas and noted approximations. Use it for planning and checks; confirm safety-critical decisions with official sources.
Can I use this on mobile?
Yes. Layouts are responsive for phones and tablets on deck or in the cockpit.
