  • Magnetic Declination Calculator – True North vs Magnetic North Offsets . . .
    The Magnetic Declination Calculator provides the angular difference between true north (geographic north) and magnetic north at any location on Earth, based on the World Magnetic Model (WMM) and IGRF models After inputting latitude, longitude, altitude, and date, the tool returns the local declination (in degrees), along with the direction (east or west), the annual change rate, the adjusted
  • Declination Demystified: Adjusting Your Compass for Accurate Navigation
    Learn what declination is and how to adjust your compass for accurate navigation Understand east vs west declination, map readings, and the science behind magnetic north
  • Sun Position Calculator - See Solar Coordinates and a Sky Dome . . . - DQYDJ
    Azimuth measures the sun's compass bearing from true north (0°), moving clockwise through east (90°), south (180°), and west (270°) The calculator provides both true azimuth (based on geographic north) and magnetic azimuth (corrected for your location's magnetic declination)
  • Interactive Magnetic Declination Calculator: Click Any Location to See . . .
    Find magnetic declination for any location worldwide Click the map to instantly see true north vs magnetic north — essential for compass use navigation
  • Magnetic Declination Calculator - Online Compass
    Free browser-based magnetic declination calculator Compute the 2026 angle between True North and Magnetic North for any latitude and longitude using the World Magnetic Model (WMM-2025) Works on any phone or desktop, no install required
  • Calculation of sun’s position in the sky for each location on the earth . . .
    Azimuth indicates an angle between a point and a reference plane Generally is the angular distance of a point from the true North (geographic north) not magnetic, I made this choice, because in this way you can see the sun’s position in the map, if you use a compass, you must add the magnetic declination for your location
  • Magnetic Declination Calculator
    Calculinohub's Magnetic Declination calculator is designed to take the guesswork out of converting between true north and magnetic north — a critical adjustment for anyone working with compasses, maps, or directional instruments
  • Understanding declination correction - Suunto
    Adjustable declination correction is set once when starting to navigate by turning the North arrow in the bottom of the capsule to the angle that corresponds with your local declination
  • Magnetic Variation Calculator
    Calculate magnetic variation (declination) for any location and date with our accurate magnetic variation calculator Understand true north vs magnetic north for navigation and surveying
  • NCEI Geomagnetic Calculators
    Declination results are typically accurate to 30 minutes of arc, but environmental factors can cause magnetic field disturbances The calculator provides an easy way for you to get results in HTML, XML, CSV, or JSON programmatically (API)
