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 time to see watts, calories and finish times for common test distances. You can also start with watts, time or distance.
Run the numbersCompare raw erg scores with Concept2 weight-adjusted times and an illustrative age adjustment. Includes example bands and clear limits.
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 paceCompare predicted splits from 500m to half marathon and equal-pace reference times. Includes illustrative training-zone bands and printable tables.
View the chartEstimate a 2k time from a longer test. Compare three model scenarios and a target split time, then check the estimate against real results.
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 powerChoose an illustrative starting drag factor, then check the monitor reading and stroke feel. Explains why the damper setting is not a fixed drag value.
Choose drag factorCalculate a Concept2 weight-adjusted erg score from body weight and actual time. Keep the original result for online rankings.
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 DPSConvert mechanical work in kJ and session duration into estimated Concept2 monitor Calories. Includes the inverse calculation and worked examples.
Convert kilojoulesEstimate VO2 max from a maximal 2k test, body weight and training level using Concept2 equations. Includes worked examples and model limits.
Estimate VO2maxCompare rowing and running pace using two illustrative models. Choose the intended effort and work duration before using a substitution.
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 conversion tools explain the Concept2 formulas they use. Predictions and training suggestions also state their assumptions. Keep calculated results beside real session data, as clubs such as Oundle Town Rowing Club do when reviewing progress. A calculator helps with one result; your club records provide the wider context.
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.
Choose the rowing calculator that matches your question. A pace calculator converts distance, total time and split time. A score calculator applies a comparison method to a recorded result. A pace predictor estimates a different test distance. Keeping those jobs separate makes the output easier to use in a training session.
Choose a tool from the input you already have. Split time means the time per 500 meters. The pace tool converts split time into finish time; the chart compares that split time across distances. The score tool compares raw and adjusted results. Use a completed test for training targets and keep estimated results labelled as estimates.
| Your question | Start here | Have ready |
|---|---|---|
| What split time do I need? | Erg pace calculator | Distance and total time |
| What power does that split require? | Watts to split converter | Watts or average 500m split |
| How should I compare scores? | Erg score calculator | Raw time, distance and body weight |
| What pace should I train at? | Training pace calculator | A recent 2k test |
| What should the club check before rowing? | Rowing risk assessment | Venue, participants and local controls |
These tools explain their formulas and assumptions on the individual pages. Calculated examples are not official rankings. For a competition comparison, use a current ranking filtered by distance, age group and category, and submit your raw score.
Start a pace calculation in the erg pace calculator then use the result to check your target finish time.
For endurance-based estimates, open the 2k prediction calculator and enter a completed test.
Before an on-water session, review the rowing risk assessment tool with the person responsible for club safety.
