Bring the numbers from a morning practice or erg test here. These 13 calculators follow Concept2 split conventions and use the same core calculations found in the Row HQ coach dashboard. Junior, masters and collegiate programs can check one athlete without opening an account.
Use this page when a practice sheet gives you one number and you need another. Each tool runs in your browser without an account. Turn /500m pace into watts, set training ranges from a 2k, compare erg results, or estimate a race target. The calculations keep rowing metric and follow Concept2 split conventions for junior, masters and collegiate programs.
Practice pace and testing
Type a /500m split to see watts, calories and finish times for common test distances. You can also start with watts, time or distance.
Run the numbersAdjust a 2k, 5k or 6k result for body weight and age. Use the percentile view during junior, masters or collegiate testing blocks.
Check a scoreStart with a 2k split and produce UT2, UT1, AT, TR and AN pace ranges, stroke rates and interval pieces for the next practice.
Set practice pacePlot projected results from 500m through marathon distance. Training bands make the chart easy to save for a team briefing.
View the chartUse a 5k, 6k, 10k or 30-minute test to estimate a 2k. Confidence bands and target splits turn the result into a practical race plan.
Set a 2k targetPower and machine setup
Move between watts and /500m pace in either direction. The reference table helps coaches hand out power targets across a training group.
Convert powerFind a Concept2 drag-factor range from body weight, experience and purpose. The guidance explains why a higher damper is not automatically better.
Choose drag factorPut lightweight and openweight 2k performances on a comparable scale with the Concept2 weight-adjustment calculation.
Adjust the resultConditioning and cross-training
Calculate distance per stroke from rate and split. Reverse the inputs when a practice calls for a set DPS and rating.
Calculate DPSTurn PM5 kilojoules into estimated session calories with the Concept2 equation. The converter also works backward for planning.
Convert kilojoulesEstimate VO2max from 2k time, body weight and sex with the Klusiewicz 2016 regression, then review trained-rower benchmark bands.
Estimate VO2maxCompare a rowing /500m split with running pace per mile or kilometer. Two sourced methods show the range instead of claiming exact equivalence.
Compare pacesA Concept2 ergometer gives a reliable result, but turning one score into splits, watts and predictions can mean a stack of spreadsheets and forum formulas. An athlete should be able to search for an "erg pace calculator" before practice, enter a split and get a clear answer. That simple job is why we collected the calculations here.
The underlying pace, power and prediction methods are the same ones used by Row HQ. They also support the club data reviewed at Oundle Town Rowing Club. One calculator can help one athlete. A program still needs a database to retain training history, compare tests and give coaches current lineup information across junior, masters and collegiate groups.
A missing rowing calculation is useful feedback. Send the details through our contact form so we can decide if it belongs beside the 13 tools already available.
One athlete can use a calculator before practice. A coach overseeing several program levels needs each test connected to the right person and training history. Row HQ is club management software for that wider job. It brings training, coach and admin work together while these public tools stay free for quick individual checks.
Review Row HQ pricing, then explore practice and session tracking, coach tools and the admin dashboard. The Oundle Town RC case study shows the system in use. The spreadsheet comparison shows what changes when records move into one platform.
Choose the calculation that matches the question. Use the erg pace calculator for /500m pace, watts, calories or finish time. Open the erg score calculator for weight and age context. Pick the training pace calculator when a coach needs zones and interval targets. All three run in the browser without an account.
No. All 13 calculators are free, work in a browser and ask for no signup. A junior athlete can check a test, a masters rower can compare training pace and a collegiate coach can verify a split without creating a Row HQ account. Row HQ club management software is separate from this public calculator library.
Pace and power use the Concept2 equation watts = 2.80 / (split_seconds / 500)^3. Calorie estimates use kcal/hr = (watts * 4) + 300. Predicted distance times use the Riegel model T2 = T1 * (D2 / D1)^1.06. Each calculator identifies the method it applies.
Yes. The tools work in any current browser, including a phone used beside the ergs or at the dock. Rowing distances remain metric, and erg pace stays in the worldwide /500m convention. You do not need to download an app or sign in before checking a practice target.
Public calculators answer one athlete's question at a time. A junior, masters or collegiate program also needs training records, coach access and admin work connected across its roster. Row HQ is club management software for that shared work. The calculator library remains open for the quick checks athletes and coaches make around practice.
Use the rowing glossary when a term on a practice sheet needs context. Start with the ergometer, then compare a rowing shell with a scull. The guides to rowing boat types, a regatta, the role of a coxswain and catching a crab cover the language used around the team.
Start free with up to 20 athletes.
Use every Row HQ feature with your own shells, squads, and practices. No card. No time limit.
