This helper template provides a way to convert geographic coordinates from degree, minute, second format to decimal degrees. It is intended for use in building infobox templates.
Usage[edit source]
The template can be used with named or unnamed parameters as shown.
| Parameter | Description |
|---|---|
{{decdeg
| deg =
| min =
| sec =
| hem =
| rnd =
}}
|
Degrees Minutes Seconds Hemisphere Round |
Input degrees can be signed in which case the hemisphere is not required. A negative value implies a value in the western or southern hemisphere. Minutes and seconds need not be specified. If no degrees are specified then a value of zero is assumed. This template does not attempt to trap invalid values and results in this case might be undefined.
The decimal precision of the result is determined by the value assigned rnd, which defaults to 7.
Currently this template does not attempt to trap invalid values.
Examples[edit source]
- {{decdeg|deg=37|min=51|sec=00|hem=N}} → 37.85
- {{decdeg|deg=119|min=34|sec=04|hem=W}} → -119.5677778
When using unnamed parameters, the hemisphere must be the fourth parameter:
- {{decdeg|37|51||N}} → 37.85
- {{decdeg|119|34||W}} → -119.5666667
Input can be signed or unsigned decimal degrees:
- {{decdeg|37.85|||N}} → 37.85
- {{decdeg|119.5666667|||W}} → -119.5666667
- {{decdeg|37.85}} → 37.85
- {{decdeg|-119.5666667}} → -119.5666667
When using rounding, the factor must be the fifth parameter:
- {{decdeg|37.85||||1}} → 37.9
- {{decdeg|-119.5666667||||1}} → -119.6
If a value is undefined then zero is assumed:
- {{decdeg||51||N}} → 0.85
- {{decdeg||34||W}} → -0.5666667
Negative zero values are accommodated:
- {{decdeg|0|51}} → 0.85
- {{decdeg|-0|34}} → -0.5666667
