How to Find Curved Distances on Maps
- 1). Place one end of the string on the map's starting point.
- 2). Lay the string along the map, covering the route's every curve.
- 3). Grip the point of the thread that marks the route's end point with the fingernails of your thumb and forefinger. Grip the thread's other end with your other hand.
- 4). Stretch the thread until it becomes taut.
- 5). Lay the thread along the ruler to measure it.
- 6). Convert this measurement to real-life distance using the map's scale. If an inch on the map represents a mile, and the string measures 8 inches, the route is 8 miles long.
