The Mileage Calculator estimates the distance between two major cities, with an approximate driving distance and flight time.
New York, NY to Boston, MA: 190.2 miles (306.1 km) in a straight line
| Straight-line distance | 190.2 miles / 306.1 km |
| Typical driving distance (≈ ×1.2) | 228 miles |
| Flight time (at ~500 mph + 30 min) | 0.9 hours |
The calculator measures the great-circle ("as the crow flies") distance using latitude and longitude. Roads rarely run straight, so driving distance is usually 10–30% longer; the result shows a typical estimate of 1.2 times the straight-line distance. For exact routes, use a map service.
Worked example (defaults): New York to Boston is about 190 miles in a straight line and roughly 215 miles by road.
Many employers and tax authorities reimburse or deduct driving at a standard rate per mile. In the U.S., the IRS publishes a business mileage rate each year (around 70 cents per mile recently). Keep a log of date, purpose, start and end points and miles.
Combine the distance with the Fuel Cost or Gas Mileage Calculator to estimate fuel spending.
