What is the formula for converting knots to nautical miles?
1 knot is equal to 1 nautical mile per hour. To convert knots to nautical miles, simply multiply the speed in knots by the time in hours. For example, if a boat is traveling at 10 knots for 4 hours, it would cover 40 nautical miles.
How many miles are there in 10 degrees?
A degree is about 69 nautical miles, so 690.
How fast is knot in kmph?
If you go at one knot, then you're covering one nautical mile/hour. One nautical mile is 1852 meters, or 1,852 kilometers. So if you're going at 10 knots, you're doing 18.5 km/h.
How do you read a wind barb on a hurricane map?
The main stem of a wind barb points in the direction that the wind is blowing from. The barbs show the wind speed to the nearest 5 knots. A half barb indicates 5 knots, a full barb indicates 10 knots, and a flag indicates 50 knots. To get the wind speed you add the numbers presented by the barbs. So, for example, if you have a full barb, and a half barb you ad 10+5 to get 15 knots. If you have a flag, 2 full barbs, and a half barb, you add 50+10+10+5 and get 75 knots. To convert to miles per hour multiply the wind speed in knots by 1.15. Wind speeds in mph are usually rounded to the nearest 5 mph as well. So 75 knots would be about 85 mph.These barbs can be found on many weather maps, not just hurricane maps.
How fast is 8-9 knots an hour?
