Use this result well
A quick decision brief for this specific tool
Inputs that matter
One de-identified completed swim record and basis; named course/segment, timing-method, accepted-distance and independent-summary sources; recorded metres or yards unit; completed distance; elapsed clock; and independent same-record pace/100 clock
Output to expect
Preserved provenance, elapsed seconds, 100-unit distance blocks, reproduced pace clock and seconds per 100, same-unit average speed, independent pace and signed same-record pace difference
How it works
Validate every source field and strict clock token, convert the elapsed clock with 60 seconds per minute, divide by recorded distance/100, then compare the separately prepared pace for the identical record
Confirm distance, unit, elapsed clock and independent pace belong to the same exact completed segment, course context, timing method and pre-existing inclusion decision. Reconcile metre and yard records separately rather than converting course performance.
Use the signed difference only for arithmetic review. Official-time status, timing-system validity, course approval, swimmer classification, training, race/open-water prediction, health and safety require the original evidence, applicable rules and qualified judgment.
Choose your path
Built around the job you need to finish
Reproduce pace per 100 for one completed, source-labelled swim distance/time record and compare a separately prepared pace for that identical record without converting course performance or prescribing training.
Swimmer checking one completed training-log segment
Catch a copied distance, clock or pace-summary mismatch without receiving an ability rating or workout target.
Name the completed segment, course context, timing method and included distance, then copy the recorded unit, distance, elapsed clock and independent pace clock.
Sees the reproduced pace clock, seconds per 100 and signed arithmetic difference while training, health and race decisions remain outside the worksheet.
Coach or meet volunteer reviewing a published result
Keep timing and result provenance visible while checking a copied pace summary without certifying official status.
Select the published-result basis, preserve the exact event/course and timing-method record, trigger a malformed-clock error, recover and save only the reviewed reconciliation.
Can distinguish arithmetic agreement from timing-system validity, course approval, legal completion and official-result acceptance.
Analyst reconciling separate metre and yard records
Avoid presenting physical length conversion as equivalent pool-course performance.
Run each completed source record independently in its recorded unit and compare only the same-record independent pace before exporting the evidence boundary.
Receives auditable same-unit arithmetic without universal course conversion, swimmer classification, race prediction or open-water allowance.
Authoritative checks for this tool
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Name the exact completed source, pool or course context, timing method and pre-existing inclusion decision. Do not pool metre and yard records or change the included segment after seeing the arithmetic.
One result or log segment = one distance unit + one accepted distance + one elapsed clock
Parse the Recorded Clock Strictly
Enter MM:SS.sss or H:MM:SS.sss with the seconds field below 60. NIST's time table defines one minute as 60 seconds; formatting from total hundredths prevents invalid clock displays such as 1:60.
Report the pace clock, seconds per 100 and same-unit average speed, then subtract the independently recorded pace seconds. The signed difference is an arithmetic review flag only.
Pace seconds/100 = elapsed seconds ÷ (recorded distance ÷ 100)

Example Scenarios
A de-identified log contains 1500 m in 25:30.00 and a separate 1:42.00/100 m summary. Reproducing zero difference confirms only that the two arithmetic summaries agree.
A reviewer retains the published event/course and timing-method record, copies the accepted distance and elapsed clock, and investigates a nonzero pace difference against the separate result summary.
A 1000 yd source record is reconciled in yards and labelled per 100 yd. It is not converted into an equivalent metre-course performance or used to predict another swim.
FAQ
No. Zero means only that the displayed arithmetic matches the independent pace for the same entered record. Official-time status, timing equipment, course approval and result acceptance belong to the source and applicable rules.
No. It labels and checks the unit already used by the source record. Physical length conversion cannot make performances from different courses, turns, timing contexts or swims equivalent.
Use exactly the elapsed clock and accepted distance defined by the completed source record. This worksheet does not decide whether rest, a split or a segment should have been included.
This worksheet provides no ability rating or benchmark. Compare only against the relevant official standards or goals chosen from the full swimmer, event and program context.
Not by itself. It does not model stroke, turns, rest, current, navigation, conditions, health or safety. Keep planning and consequential decisions with the original evidence and appropriately qualified people.
About Swim Pace Calculator
Use this worksheet to reproduce pace per 100 from one exact completed distance-and-time record in its recorded metres or yards unit, then compare an independently prepared pace for that identical record. Preserve the source's course, segment, timing method, accepted distance and precision. Arithmetic agreement does not certify an official time, compare unlike courses, classify a swimmer or create a training or race plan.
