FAQ

What UTM zone is Singapore in?

Singapore is in UTM zone 48N, with central meridian 105° E. In WGS 84, the city center is at E 372,065 m and N 142,576 m.

What is the magnetic declination in Singapore?

Today the magnetic declination in Singapore is 0.24° E, changing by +1.9′ per year (WMM2025 model). To get the true azimuth, add the declination to the magnetic azimuth (East positive, West negative).

What is the geoid undulation in Singapore?

The geoid undulation (EGM2008) in Singapore is N = 8.17 m. To convert a GNSS height (ellipsoidal, h) to an approximate orthometric height: H = h − N.
