DMS 计算器(度、分、秒)

表达你的爱:

The DMS Calculator is a tool used to convert between different angular measurement formats, such as Degrees, Minutes, and Seconds (DMS), Decimal Degrees, Radians, and Gradians. This calculator helps professionals, students, and hobbyists accurately convert angles for navigation, surveying, astronomy, and engineering applications.

Formulas DMS Calculator

十进制度 转换为 DMS

Degrees = Floor(Decimal Degrees)
Minutes = Floor((Decimal Degrees - Degrees) × 60)
Seconds = ((Decimal Degrees - Degrees) × 60 - Minutes) × 60

地点:

  • Floor() represents the integer part of a decimal number
  • Decimal Degrees is the angle in decimal form (e.g., 45.5°)
  • Degrees is the whole degree value
  • Minutes 范围从 0 到 59
  • Seconds ranges from 0 to 59.999...

DMS 到十进制度

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

地点:

  • Degrees is the whole degree value
  • Minutes 范围从 0 到 59
  • Seconds ranges from 0 to 59.999...
  • Decimal Degrees is the resulting angle in decimal form

Radians to DMS

Decimal Degrees = Radians × (180 / π)

Then apply Decimal Degrees to DMS conversion.

DMS to Radians

Decimal Degrees = Degrees + (Minutes / 60) + (Seconds / 3600)
Radians = Decimal Degrees × (π / 180)

地点:

  • π (pi) 大约是3.14159265359
  • Radians is the angle in radian form

Gradians to DMS

Decimal Degrees = Gradians × (9 / 10)

Then apply Decimal Degrees to DMS conversion.

DMS to Gradians

Decimal Degrees = Degrees + (Minutes / 60) + (Seconds / 3600)
Gradians = Decimal Degrees × (10 / 9)

地点:

  • Gradians is the angle in gradian form (400 gradians in a full circle)

DMS to Decimal十进制度 = 度 + (分 / 60) + (秒 / 3600)45° 45' 00" = 45.75°
Radians to DMSDecimal Degrees = Radians × (180 / π)1 rad = 57.2958°
DMS to RadiansRadians = Decimal Degrees × (π / 180)180° = π rad
Gradians to DMSDecimal Degrees = Gradians × (9 / 10)100 grad = 90°
DMS to GradiansGradians = Decimal Degrees × (10 / 9)90° = 100 grad

Example of DMS Calculator

Convert 48.2564° to DMS

Degrees = Floor(48.2564) = 48°
Minutes = Floor((48.2564 - 48) × 60) = 15'
Seconds = ((48.2564 - 48) × 60 - 15) × 60 = 23.04"
Result: 48° 15' 23.04"

最常见的常见问题解答

2. How accurate is a conversion between DMS and Decimal Degrees?

The conversion is highly accurate as long as all calculations maintain precision up to at least six decimal places, which is standard for scientific applications.

3. Can I use this calculator for GPS coordinates?

Yes, the DMS Calculator can convert GPS coordinates between DMS and Decimal Degrees formats, which is essential for mapping and navigation applications.
