# Degrees To Decimal With Javascript

I have found a nice way to get decimal value from degrees of longitude and latitude recently:

```
function format(coords) {
var decimal = 0,
output = [],
coords = coords.split(' '); // it might be <br> as well
for (var i = 0; i < coords.length; i += 1) {
var c = coords[i].split(' ');
for (var j = 0; j < c.length; j += 1) {
decimal += c[j] / Math.pow(60, j);
}
output.push(parseFloat(decimal).toFixed(5));
decimal = 0;
}
prompt('Souřadnice bodu', output.join(', '));
}
```

When you call `format("DD° MM' SS' DD° MM' SS'");`

you’ll get decimal value in return (or `prompt`

to be accurate). What I like the most about this solution is the usage of Math.pow(). I think it is a neat way to transform the values as you need to divide parts of latitude or longitude by 60^{0}, 60^{1} and 60^{2} respectively.

There is definitely a googol of different solutions to this task, I just liked the simplicity of this one.
