This needs KMPL (Kilometre per litre) as a unit and more currencies instead of Euro for the calculation. Also it's not clear what currency Price (p/litre) is. Rest, it's a handy tool! Thanks for creating this.
@edward_bowden It'd be great if the map would be more responsive/draggable and if we could adjust the currency and other measures 🙌
Also, have you planned on making a version of this for electric cars? ⚡🔋
stoic.
