Calculate total distance from laps on a 400 m track, pool or custom lap length, or find how many laps make a distance in km, miles or meters.
| Course | Enter for one length | Enter for down and back | Example total |
|---|---|---|---|
| 25-meter pool | 25 m | 50 m | 40 lengths = 1,000 m |
| 50-meter pool | 50 m | 100 m | 30 lengths = 1,500 m |
| 25-yard pool | 22.86 m | 45.72 m | 40 lengths = 1,000 yd |
Swimming terminology is not universal: some people call one pool length a lap, while others mean a down-and-back trip. Decide which convention your lap count uses and enter the matching lap length. Pick a standard track or pool length, or choose Custom and enter your own lap length in meters, feet, yards or miles.
Lap Distance Formula
The following formula is used to calculate the Lap Distance.
- Where Dlap is the Lap Distance (m)
- TD is the total distance (m)
- L is the total number of laps
To calculate the lap distance, divide the total distance by the number of laps.
How to Calculate Lap Distance?
The following example problems outline how to calculate Lap Distance.
Example Problem #1:
- First, determine the total distance (m).
- The total distance (m) is given as 1500.
- Next, determine the total number of laps.
- The total number of laps is provided as 10.
- Finally, calculate the Lap Distance using the equation above:
Dlap = TD / #L
The values given above are inserted into the equation below and the solution is calculated:
Dlap = 1500 / 10 = 150 (m)
Example Problem #2:
For this problem, the variables needed are provided below:
total distance (m) = 1600
total number of laps = 20
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
Dlap = TD / #L = ?
