How to Use This Calculator
Input speed
Enter the speed in knots or any other unit in the dropdown.
Select mph output
Choose miles per hour as the target unit to match overland speedometers.
Review equivalents
The quick reference grid provides km/h and m/s conversions at the same time.
Formula
mph = knots × 1.15078
km/h = knots × 1.852
m/s = knots × 0.514444
All conversions use the exact definition of a nautical mile: 1,852 meters.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Aviation and marine charts rely on knots, but ground operations usually reference mph. This converter keeps everyone aligned by translating to mph instantly, while still showing the equivalent metric values.
Perfect for drone operators switching between FAA paperwork and consumer displays, or for sailors discussing speeds with shore support who think in mph.
Since the tool converts via meters per second internally, rounding is consistent regardless of the sequence of units you choose.
Frequently Asked Questions
How many mph in 1 knot?
Approximately 1.15078 mph. The calculator uses that exact factor for high precision.
Why convert through meters per second?
Using m/s as an intermediate ensures all units remain consistent and avoids compounded rounding errors.
Will it work for headwinds and tailwinds?
Yes. Negative values simply indicate direction; magnitudes still convert correctly.
Can I export the results?
Copy the displayed numbers into flight plans or spreadsheets. Future enhancements may include direct export options.
