Scientific Calculator Degrees and Minutes

Degrees, minutes, and seconds (DMS) are a system of angular measurement used in navigation, astronomy, and surveying. This calculator helps you convert between degrees, minutes, and seconds with precision.

What are Degrees, Minutes, and Seconds?

The degrees, minutes, seconds (DMS) system divides a full circle into 360 degrees. Each degree is divided into 60 minutes, and each minute is divided into 60 seconds. This system provides more precise measurements than decimal degrees alone.

Example: 45°30'15" means 45 degrees, 30 minutes, and 15 seconds.

Why Use DMS?

DMS is commonly used in fields like:

Navigation (GPS coordinates)
Astronomy (celestial coordinates)
Surveying and cartography
Geographic information systems

Conversion Formulas

Here are the key conversion formulas between degrees, minutes, and seconds:

Degrees to DMS

1. Take the decimal part of the degrees and multiply by 60 to get minutes.

2. Take the decimal part of the minutes and multiply by 60 to get seconds.

3. Round the seconds to the desired precision.

DMS to Degrees

1. Convert minutes to degrees: minutes ÷ 60

2. Convert seconds to degrees: seconds ÷ 3600

3. Add all parts together: degrees + (minutes ÷ 60) + (seconds ÷ 3600)

Example Conversion

Convert 45.5041667° to DMS:

0.5041667° × 60 = 30.25 minutes
0.25 × 60 = 15 seconds
Result: 45°30'15"
