Keep the calculations used through winter erg work and the racing season in one browser page. The 13 tools follow Concept2 split conventions for river and coastal rowers. Row HQ carries the same core maths into its coach dashboard when a community club needs joined-up records.
Irish rowers can make 13 common calculations here without creating an account. Convert /500m split and watts, produce training zones, compare a weight-adjusted erg result, or project a 2k from a longer test. The tools run in any browser and retain rowing metric, so they suit winter indoor work as well as river and coastal club training.
Erg tests and race targets
Enter a /500m split for watts, calorie rate and projected finish times. The calculation also works back from power, time or distance.
Convert the splitReview a 2k, 5k or 6k score after applying bodyweight adjustment and age grading for a wider testing comparison.
Place the scoreSet UT2, UT1, AT, TR and AN targets from a 2k split, including rates and interval pieces for indoor and on-water sessions.
Set training paceSee projected times between 500m and marathon distance on one chart, with coloured bands for different training intensities.
Read the chartEstimate a 2k from 5k, 6k, 10k or 30-minute work. Confidence ranges and target splits give the next test a clear aim.
Predict the testPower, drag and weight
Translate wattage into /500m pace, or send a split back to watts. The reference table supports coach-set power pieces.
Change pace and powerSelect a Concept2 drag-factor range using body weight, experience and training goal, with a clear damper explanation.
Select drag factorUse Concept2 weight adjustment to place lightweight and heavyweight 2k scores on a comparable footing.
Apply adjustmentWinter and crossover training
Find distance per stroke from rating and split, or enter a target DPS and rate to calculate pace.
Calculate stroke distanceConvert the kilojoules recorded by a PM5 into estimated calories with the Concept2 equation. Reverse conversion is included.
Convert the sessionEstimate VO2max from a 2k result, body weight and sex using the Klusiewicz 2016 regression and rowing benchmarks.
Estimate aerobic fitnessRelate a rowing /500m split to running pace per kilometre or mile through two sourced comparison methods.
Match run paceA winter score from a Concept2 ergometer often raises another question straight away. A rower may need watts, a target distance or the right pace for the next block. The "erg pace calculator" gathers those answers without asking a community club member to find the spreadsheet kept by one coach.
These methods also sit beneath Row HQ's club features and support real use at Oundle Town Rowing Club. There is no reason to charge for a one-off conversion. Club software becomes useful when indoor scores, river outings, coastal sessions and coach records need to stay connected across the year.
Share a recurring calculation through the contact form if it is absent from the hub. The best suggestions will come from coaches and rowers who already do the work by hand.
One free tool can answer a rower before tonight's session. Running a community club means keeping training, coaching and admin information useful for everyone involved. Row HQ is club management software for that shared work. It does not replace the 13 calculators. It connects the wider records that a calculator cannot hold.
View Row HQ pricing before exploring training management, tools for coaches and the admin dashboard. The Oundle Town RC case study gives a club example. The spreadsheet comparison explains the move away from separate files.
Use the input you already know. Open the erg pace calculator for /500m pace, watts, calories or finish time. Choose the erg score calculator to add age and weight context. The training pace calculator turns a 2k into zones and interval targets. Each tool is free in the browser.
No. All 13 calculators are free and require no sign-up. River rowers, coastal crews and winter training groups use the same metric inputs and /500m erg convention. Row HQ charges for its separate club management software, which covers training, coach and admin work across a club.
Power follows the Concept2 formula watts = 2.80 / (split_seconds / 500)^3. Estimated calories use kcal/hr = (watts * 4) + 300. Distance estimates apply the Riegel model T2 = T1 * (D2 / D1)^1.06. The selected tool names its calculation so the result can be checked.
Yes. They work in any current browser on a phone, tablet or computer. A rower can check a /500m pace beside the erg without registering or installing an app. The same metric conventions carry into on-water training when the weather improves.
A calculator returns one answer. A community club also needs training, coach and admin records to stay organised across members. Row HQ is club management software for that ongoing work. River and coastal rowers can still use the public tools whenever a single test or pace needs checking.
Find plain explanations in the rowing glossary. Begin with the ergometer, then read about a rowing shell and a scull. The page on rowing boat types sets out the wider fleet. Entries for regatta, coxswain and catching a crab cover other language heard around a club.
