Scientific Calculator Online with Degrees Minutes and Seconds

This scientific calculator handles degrees, minutes, and seconds (DMS) for precise angle measurements. It performs trigonometric, logarithmic, and other calculations while maintaining the DMS format throughout operations.

How to Use This Calculator

Enter your angle in degrees, minutes, and seconds format in the input field. Select the operation you want to perform (sine, cosine, tangent, etc.). The calculator will convert the angle to decimal degrees, perform the calculation, and display the result in both decimal and DMS formats.

Formula Used

Decimal degrees = Degrees + (Minutes / 60) + (Seconds / 3600)

DMS result = Convert the decimal result back to degrees, minutes, and seconds

Example Calculation

Input: 45° 30' 15" (sine function)

Calculation: 45 + (30/60) + (15/3600) = 45.5041667°

Result: sin(45.5041667°) ≈ 0.7115 (0° 42' 41.4")

Angle Conversion Basics

Degrees, minutes, and seconds (DMS) is a format used to represent angles with more precision than decimal degrees alone. One degree equals 60 minutes, and one minute equals 60 seconds.

Format	Example	Precision
Degrees	45°	1 decimal place
Decimal Degrees	45.5041667°	7 decimal places
Degrees Minutes Seconds	45° 30' 15"	Up to seconds

The DMS format is commonly used in navigation, astronomy, and surveying where precise angle measurements are required.

Scientific Functions

This calculator supports a wide range of scientific functions including:

Trigonometric functions (sine, cosine, tangent)
Inverse trigonometric functions (arcsine, arccosine, arctangent)
Logarithmic functions (natural log, base-10 log)
Exponential functions
Square root and power functions

Note

All calculations maintain the DMS format throughout operations. The calculator automatically converts between DMS and decimal degrees as needed for the selected function.

Common Uses

This calculator is particularly useful for:

Navigation and surveying
Astronomical calculations
Engineering measurements
Geographic coordinate conversions
Any application requiring precise angle calculations
