About ToRoute

Working with a position on a map quietly turns into a maths problem. One app hands you a coordinate in decimal degrees while the chart on the wall is marked in degrees, minutes, and seconds. You know two points but not the distance between them, or the heading to set off on, or where the true half-way point falls. You want to know when you’ll actually arrive and what the fuel will cost before you commit to a route. None of it is hard once someone lays out the formula — but the formulas are scattered, and doing them by hand, for every leg, is where planning turns into a chore.

ToRoute exists to take that arithmetic off your plate. Rather than one long guide you have to read end to end, the site is built around a set of small, single-purpose calculators, each aimed at one question about position and route. The Distance Between Coordinates tool gives the great-circle distance between two latitude/longitude points with the Haversine formula, in kilometres, miles, and nautical miles. The Initial Bearing & Heading Calculator returns the heading to steer from one point to another, in degrees from true north with a compass direction. The Coordinate Converter moves a coordinate between decimal degrees and degrees-minutes-seconds in either direction, with the right hemisphere. The ETA & Journey-Time Calculator turns a distance and an average speed into a journey time and an arrival clock time. The Fuel Cost Calculator estimates the fuel a route needs and what it costs from your economy and the pump price. And the Geographic Midpoint Calculator finds the true half-way point along the great-circle route between two places.

Beyond the calculators, the blog and learn section cover satellite positioning, maps and coordinates, route planning, and the devices and apps that guide you, along with the reasoning behind the numbers the tools produce. The Museum of Navigation is a browsable collection of the satellite systems that fix a position, the maps and projections that put the world on a page, the instruments that point the way, and the landmarks and methods people navigated by for centuries, with every entry, image, and fact drawn from Wikipedia and Wikimedia Commons.

A few things worth stating plainly. ToRoute is an independent site — not a mapping authority, a surveyor, or a device manufacturer, and not affiliated with any GPS, mapping, or navigation brand. It is supported by advertising, which is how the tools stay free with no account required. Every figure the tools produce — a distance, a bearing, a converted coordinate, an ETA, a fuel cost, a midpoint — is an educational estimate built on the values you enter and standard spherical-Earth formulas, not a survey-grade measurement or official guidance. For anything that must be precise or safety-critical — navigation at sea or in the air, surveying, or an emergency — confirm against your calibrated instruments, an official chart, and the correct map datum. If a tool looks off, or there’s a calculator you wish existed, the contact page is the place to say so.
