measure the distance between two coordinatesCalculators
Great-circle distance between two latitude/longitude points.
This decimal degrees to DMS converter turns GPS coordinates like 35.6892, 51.3890 into 35° 41′ 21.12″ N, 51° 23′ 20.4″ E, and reads DMS or decimal minutes back into decimal degrees.
Accepts 35°41'21.1"N, 35 41 21.1 N, N 35 41.352 (decimal minutes), or −35.6892. Put latitude first when you enter a pair.
D = whole part of |decimal| M = whole part of (|decimal| − D) × 60 S = ((|decimal| − D) × 60 − M) × 60
The sign becomes the hemisphere: positive latitude is N and negative is S; positive longitude is E and negative is W. Going back:
decimal = D + M/60 + S/3600 (negative for S and W)
| Decimal degrees | DMS | Distance at the equator |
|---|---|---|
| 0.1° | 6′ | about 11 km |
| 0.01° | 36″ | about 1.1 km |
| 0.001° | 3.6″ | about 111 m |
| 0.0001° | 0.36″ | about 11 m |
| 0.00001° | 0.036″ | about 1.1 m |
Five decimal places in decimal degrees, or two decimals of a second in DMS, pin a point to about a meter.
Decimal degrees (35.6892) are what web maps and most apps use. Degrees, minutes, and seconds (35° 41′ 21.12″ N) appear on paper maps, in surveying, and in aviation. Degrees and decimal minutes (35° 41.352′ N) are common on marine and handheld GPS units. All three describe the same point; only the way the fraction of a degree is written changes.
Take the whole degrees, multiply the remainder by 60 for minutes, then multiply what is left of the minutes by 60 for seconds.
Add degrees + minutes/60 + seconds/3600, and make it negative for S or W.
Latitude (north-south) usually comes first, then longitude (east-west).
