An easy "rule of thumb" is that a nautical mile is 15% longer than a statute mile, so if you multiply statute miles by 1.15 you will have a close approximation.
To convert knots to miles per hour, you can multiply the speed in knots by 1.15078. Therefore, 70 knots is approximately 80.6 miles per hour.
mph x 0.868976242 = knots per hour
49 knots=56.388193 miles per hour
439 knots=505.192178 miles per hour
11 knots=12.6585739 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.
To convert knots to miles per hour, you can multiply the speed in knots by 1.15078. Therefore, 70 knots is approximately 80.6 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
