Online Scientific Calculator with Degrees Minutes Seconds

This online scientific calculator handles degrees, minutes, and seconds (DMS) conversions with precision. Whether you need to convert decimal degrees to DMS or vice versa, this tool provides accurate results for scientific and navigational applications.

How to Use This Calculator

To use the calculator:

Select the input format (Decimal Degrees or Degrees Minutes Seconds)
Enter your value in the input field
Select the output format you want to convert to
Click "Calculate" to see the result

The calculator will display the converted value in the selected format. You can also reset the form to start over.

Note: This calculator assumes positive values. For negative coordinates, you can manually add the negative sign to the result.

Conversion Formulas

The calculator uses these standard conversion formulas:

Decimal Degrees to DMS

Degrees = Integer part of decimal degrees

Minutes = (Decimal part × 60) without the integer part

Seconds = (Remaining decimal part × 60)

DMS to Decimal Degrees

Decimal Degrees = Degrees + (Minutes ÷ 60) + (Seconds ÷ 3600)

For example, converting 45.75 degrees to DMS:

Degrees = 45
Minutes = 0.75 × 60 = 45
Seconds = 0 × 60 = 0
Result: 45°45'0"

Common Uses

FAQ

What is the difference between decimal degrees and DMS?: Decimal degrees represent angles as a single decimal number (e.g., 45.75°), while DMS (Degrees Minutes Seconds) breaks it down into degrees, minutes, and seconds (e.g., 45°45'0").
Can I convert radians to DMS using this calculator?: Yes, the calculator can convert between decimal degrees, DMS, and radians. Simply select the appropriate input and output formats.
Is this calculator accurate for scientific work?: Yes, the calculator uses standard conversion formulas and provides precise results suitable for scientific and navigational applications.
Can I use negative values with this calculator?: The calculator assumes positive values. For negative coordinates, you can manually add the negative sign to the result.
How do I interpret the DMS format?: The DMS format is written as degrees (°), minutes ('), and seconds ("). For example, 45°45'0" means 45 degrees, 45 minutes, and 0 seconds.
