Calculate total distance, number of laps, or lap length from the other two values with meter, kilometer, and mile results.
| 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. This calculator’s fixed distance inputs use meters for lap length and kilometers for total distance.
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 = ?
