To convert 700 knots to miles per hour (mph), we use the conversion factor where 1 knot equals 1.15078 miles per hour. Thus, 700 knots is equivalent to 700 * 1.15078 miles per hour.
Calculation and Conversion
The calculation involves multiplying 700 by 1.15078. This gives us 700 * 1.15078 = 805.546 miles per hour. Therefore, 700 knots is equal to approximately 805.55 mph.
Understanding the Conversion Factor
The conversion factor between knots and miles per hour is based on the definition of a knot, which is one nautical mile per hour. Since a nautical mile is 6,076.1 feet and a statute mile (used in miles per hour) is 5,280 feet, the conversion between the two units of speed is not a simple 1:1 ratio.
| Unit of Speed | Conversion Factor |
|---|---|
| 1 Knot | 1.15078 mph |
| 1 mph | 0.868976 Knots |
Practical Applications
The speed of 700 knots, or approximately 805.55 mph, is exceptionally high and typically associated with military jets or experimental aircraft. For context, commercial airliners usually cruise at speeds around 450-550 knots (517 to 633 mph), while some military jets can exceed Mach 2, which is more than twice the speed of sound (approximately 1,470 mph at sea level).
Speed Comparison
To put 700 knots into perspective, consider that the fastest manned aircraft, the Lockheed SR-71 Blackbird, has a top speed over Mach 3.5, which translates to more than 2,193 mph. Thus, 700 knots, while very fast, is not the absolute highest speed achieved by aircraft but is still significantly faster than typical operational speeds for most military and all commercial aircraft.
- Commercial Airliners: 450-550 knots (517 to 633 mph)
- Military Jets: Can exceed Mach 2 (1,470 mph)
- Lockheed SR-71 Blackbird: Over Mach 3.5 (2,193 mph)
What is the primary use of the knot as a unit of speed?
+The knot is primarily used in aviation and maritime as a unit of speed because it is directly related to the nautical mile, making it convenient for navigation and communication in these fields.
How does the speed of 700 knots compare to the speed of sound?
+The speed of sound at sea level is approximately 761.2 mph. Therefore, 700 knots, which is about 805.55 mph, is slightly faster than the speed of sound (Mach 1) at sea level.
