Speed Formula:
From: | To: |
Definition: This calculator determines the speed of a boat based on the distance traveled and the time taken.
Purpose: It helps boaters, sailors, and marine professionals calculate speed in knots, which is essential for navigation and trip planning.
The calculator uses the formula:
Where:
Explanation: The distance is divided by time to calculate the average speed in knots (nautical miles per hour).
Details: Accurate speed calculation is crucial for navigation, fuel estimation, arrival time prediction, and safety at sea.
Tips: Enter the distance in nautical miles and time in hours. Both values must be > 0.
Q1: What is a knot in speed measurement?
A: One knot equals one nautical mile per hour (1.852 km/h or 1.15078 mph).
Q2: Why use nautical miles instead of statute miles?
A: Nautical miles are based on Earth's longitude/latitude measurements, making them more practical for navigation.
Q3: Can I use this for other vehicles?
A: Yes, it works for any vessel moving through water, though results are typically expressed in knots for marine applications.
Q4: How accurate is this calculation?
A: It gives average speed. Actual speed may vary due to currents, winds, and other factors.
Q5: What if my time is in minutes?
A: Convert minutes to hours (divide by 60) before entering the value.
