Move from a winter erg block to a short water season with the numbers in one place. These 13 calculators use metric rowing units and Concept2 split conventions. Their core calculations also power the Row HQ coach dashboard when a Canadian club needs to follow more than one result.
There are 13 no-account tools for common rowing questions. Turn a /500m split into power, plan training zones, compare a weight-adjusted score, or estimate a 2k from another erg test. Every calculation works in the browser and stays metric, which keeps the same format through winter indoor blocks, cross-training and the shorter Canadian water season.
Winter testing and race pace
Convert /500m pace into watts, calorie rate and finish times for standard tests. Begin with power, time or distance when needed.
Convert a paceCompare raw erg scores with Concept2 weight-adjusted times and an illustrative age adjustment. Includes example bands and clear limits.
Put the score in contextUse a 2k split time to set UT2, UT1, AT, TR and AN bands, rates and interval pieces through an indoor training block.
Create training bandsCompare predicted splits from 500m to half marathon and equal-pace reference times. Includes illustrative training-zone bands and printable tables.
View every distanceEstimate a 2k time from a longer test. Compare three model scenarios and a target split time, then check the estimate against real results.
Set the 2k goalPower, drag and score context
Exchange Concept2 watts and /500m split in either direction. The table supports power-based work across an erg room.
Translate wattsChoose an illustrative starting drag factor, then check the monitor reading and stroke feel. Explains why the damper setting is not a fixed drag value.
Configure the ergCalculate a Concept2 weight-adjusted erg score from body weight and actual time. Keep the original result for online rankings.
Adjust a performanceConditioning and cross-training
Calculate distance per stroke from rate and pace, or find the split attached to a target DPS and rating.
Check stroke distanceConvert mechanical work in kJ and session duration into estimated Concept2 monitor Calories. Includes the inverse calculation and worked examples.
Convert the PM5 readingEstimate VO2 max from a maximal 2k test, body weight and training level using Concept2 equations. Includes worked examples and model limits.
Estimate the markerCompare rowing and running pace using two illustrative models. Choose the intended effort and work duration before using a substitution.
Match a running paceA Concept2 ergometer may carry much of a Canadian club's winter programme. The monitor gives a score, but coaches still need pace, power and follow-on targets. Searching for an "erg pace calculator" should not mean a hunt through last season's workbook. We put the common conversions together for that reason.
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.
Send a missing calculation through the contact form if it keeps appearing in your club's training notes. Specific requests help us judge the next useful addition.
The free hub is built for individual answers. A club needs its erg results, training activity, coach work and administration connected to the right members. Row HQ is club management software for that continuous record. It gives volunteers and coaches one shared place while each calculator remains available for a fast check.
Compare Canadian pricing, then see the training features, coach workspace and admin dashboard. The Oundle Town RC case study shows a club using the platform. Our spreadsheet review explains the difference from separate files.
Use the erg pace calculator to move between /500m pace, watts, calories and finish time. Choose the erg score calculator for age and bodyweight context. The training pace calculator creates zones and intervals from a 2k. Together they cover the most common testing follow-ups without a login.
Yes. All 13 tools stay free and need no account. They work in a browser for winter erging, cross-training and on-water preparation. Row HQ club management software is paid separately when a club wants training, coach and admin records connected across its members.
The power conversion uses watts = 2.80 / (split_seconds / 500)^3. Estimated calorie rate follows kcal/hr = (watts * 4) + 300. Projected distance time uses T2 = T1 * (D2 / D1)^1.06. Every result page identifies its calculation.
Yes. Any current phone, tablet or computer browser can open them. A rower enters metric values and sees pace in the worldwide /500m convention. There is no account screen or app download before the result, which suits quick checks between pieces.
A browser calculator returns a single answer. A club needs winter testing, water training, coach activity and administration connected across members. Row HQ is club management software for that continuing work. The public calculators still stay available when an athlete only needs one conversion.
Open the rowing glossary for definitions used through indoor and water training. Learn what an ergometer measures, then compare a rowing shell and a scull. The index of rowing boat types leads into explanations of a regatta, a coxswain and catching a crab.
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 metres. 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.
