Swimming Pace Calculator

Calculate your swimming pace per 100 meters (or per 100 yards) given total time and distance.

Estimate the energy cost to heat your pool from its current temperature to a desired target.

Estimates your open water swim finish time based on your pool pace, race distance, water conditions, and wetsuit use.

Calculates the minimum heat pump output (in kW) needed to raise your pool to a target temperature within a set number of hours.

Compute your swimming stroke rate in strokes per minute from your lap time and stroke count.

Estimates how much it costs to heat your pool to a desired temperature based on pool volume, temperature rise needed, heater type, and energy price.

Calculates target swim training zones by combining your threshold pace and heart rate data.

Convert a swimmer's time between short course yards (SCY), short course meters (SCM), and long course meters (LCM).

Calculates the required pump flow rate (litres per hour) to achieve proper pool water turnover based on pool volume, usage level, and daily run time.

Computes your SWOLF score by adding stroke count to the number of seconds per pool length.

Quickly total your team's points for dual meets, tri-meets, or championship swim meets by entering first, second, and third place finishes.

Estimate your team's total score in a swim meet by entering first, second, and third place finishes across individual and relay events.

Calculates the hydrodynamic drag force acting on a swimmer based on velocity, body position, stroke technique, and body size.
