Distance Calculator – Add on Site
Calculate the straight‑line (great‑circle) distance between any two points on Earth with just a few clicks.
Enter the latitude and longitude of each location, hit calculate, and the result appears in kilometers – ready to copy or share on X (formerly Twitter).
How to Use the Calculator
- Open the page – the interface loads a clean, mobile‑friendly layout.
- Enter coordinates
- Lat 1 – latitude of the first point (‑90 to +90).
- Lon 1 – longitude of the first point (‑180 to +180).
- Lat 2 – latitude of the second point.
- Lon 2 – longitude of the second point.
Values can be typed manually or pasted from a spreadsheet; the fields accept decimal degrees with up to four decimal places. - Click calculate**** – the JavaScript runs the Haversine formula and displays the distance in the result box.
- Copy or share
- Click the result field to copy the value to your clipboard (a “Copied!” banner confirms the action).
- Click the 𝕏 button to post the distance directly to X with a pre‑filled tweet.
What the Calculator Measures
- Great‑circle distance – the shortest distance over the Earth’s surface, assuming a perfect sphere.
- Unit – kilometers (km). The calculation uses Earth’s mean radius of 6 371 km.
- Accuracy – the output is rounded to two decimal places, giving a precision of ± 0.01 km for most practical purposes.
