But since you want metric ~25.1 terameters.

You think you’re being witty, but you’ve just unintentionally shown why the metric system is so good.

25.1 terameters => 25,100 gigameters => 25,100,000 kilometers.

Easy as pie.

Edit: Ahh crap, I forgot about megameters. It comes out to 25,100,000,000 km. Sorry for the metric ton of confusion.
