In short,
1 knot = 1.150 799 mph (approx 1.151 mph)
and
1 MPH = 0.868 976 knots (approx 0.869 kts)
mph x 0.868976242 = knots per hour
49 knots=56.388193 miles per hour
40 knots=46.0311779 miles per hour
11 knots=12.6585739 miles per hour
36 knots=41.4280601 miles per hour
To convert 4.9 knots to miles per hour, you can multiply by 1.15078. Therefore, 4.9 knots is equal to approximately 5.64 miles per hour.
mph x 0.868976242 = knots per hour
To convert the speed boat's velocity to statute miles per hour, we know that 1 knot is equivalent to 1.15078 miles per hour. So, 35 knots * 1.15078 ≈ 40.2 statute miles per hour. To convert the auto velocity to knots, divide the speed in statute miles per hour by 1.15078. So, 35 miles per hour / 1.15078 ≈ 30.4 knots.
Use this formula to convert knots to miles per hour: knots x 1.15 = mph25.3 knots x 1.15 = about 29.11 mph
49 knots=56.388193 miles per hour
10 Miles per Hour = 8.68976241900648 Knots
41 Knots is 47.19 miles per hour.
40 knots=46.0311779 miles per hour
11 knots=12.6585739 miles per hour
36 knots=41.4280601 miles per hour
439 knots=505.192178 miles per hour
23 knots is approximately equal to 26.5 miles per hour.
