Study Notes
Knots and Speed Conversion
- A knot is defined as a speed of one nautical mile per hour.
- One nautical mile equals 1.152 statute miles.
- A statute mile consists of 5280 feet.
- There are 1609.34 meters in a statute mile.
- A nautical mile comprises 6076.12 feet.
- One nautical mile is equivalent to 1.852 kilometers.
- In meters, one nautical mile is 1852 meters.
Speed Comparisons
- Speeds expressed in Miles Per Hour (MPH) are greater than those expressed in knots.
- Conversely, speeds in knots are less than those in MPH.
Knot to MPH Conversion
- 1 knot converts to approximately 1.151 miles per hour.
- Estimating MPH from knots can be performed using Gary's Rule: Multiply the tens place by 2 and add to the knots (e.g., 37 knots = (3 * 2) + 37 = 42 MPH).
- Another estimation method: MPH = Knots minus (10's place * 2), typically resulting in values that are about 10% less accurate.
Accuracy of Estimation
- Gary's Rule maintains a 4% accuracy margin for values between 10 and 400 knots, generally yielding slightly inflated results.
Specific Conversion Examples
- 5 knots equates to 5.8 MPH.
- 10 knots equals 11.5 MPH.
- 15 knots results in 17.3 MPH.
- 20 knots is 23.0 MPH.
- 25 knots corresponds to 28.8 MPH.
- 30 knots translates to 35.6 MPH.
- 35 knots is equivalent to 40.3 MPH.
- 40 knots equals 46.1 MPH.
- 45 knots results in 51.8 MPH.
- 50 knots translates to 57.6 MPH.
- 55 knots corresponds to 63.4 MPH.
- 60 knots equals 69.1 MPH.
- 70 knots results in 74.9 MPH.
- 80 knots translates to 92.2 MPH.
- 90 knots is equivalent to 103.7 MPH.
- 100 knots equals 115.2 MPH.
