The **ERG calculator** (or **rowing calculator** if you prefer) helps you to calculate the most important parameters associated with using a rowing ergometer. You will be able to estimate your split and total time, distance, or energy in watts depending on which variables you know.

Do you work out? The bench press calculator will help you to find your one rep max for any lift, such as your squat max, deadlift max, or shoulder press max. If you want to calculate how much time it would take you to cover a particular distance, check out our ⏱️ pace calculator. We have plenty of other tools for sports freaks, so feel free to explore!

## What is an ergometer (ERG)?

The word ergometer comes from the *Greek* words *ergon* and *metron*, which mean **work** and **measure** respectively. Therefore, an ergometer is an exercise machine that measures the work performed while exercising.

The ergometer is also one of the names for an indoor rower (rowing machine), and our **rowing calculator** is for this type of ergometer in particular. The indoor rower measures the amount of energy the rower uses when exercising on the equipment. Typically, these devices display the time it takes to row 500 meters at each strokes power, called the **split rate or split**. Therefore, another name for this calculator is **ERG split calculator**.

## How to make the use of a rowing calculator?

When using indoor rowers, not all of the parameters you are interested in may be displayed. That's where the ERG split calculator comes to the rescue! **Here are the variables you can calculate**:

- Distance;
- Total time;
- 500 meters split; and
- Energy in watts.

You can also check how many calories you burn during your training session using our calories burned calculator. If you want to find your your maximum aerobic capacity, and the best heart rate zone for your exercise, visit our VO2 max and heart rate calculators.

## ERG calculator - a practical example

Using this rowing calculator is really simple. Just fill in any two of the calculator's fields, leaving out the values you want to calculate. **Let's test it with a practical example.**

John uses his indoor rower everyday. He has recently beaten his personal record, managing to get his 500 m split time down to 1 minute and 34 seconds. He wonders to himself what his total time would be if he were to keep this pace over a full 2000 meters.

- We know two values: the 500 m split time and the total distance. That's enough to use ERG split calculator.
- John did 500 m using his indoor rower in 1 minute and 34 seconds, which is 94 seconds:

`500 meters - 94 seconds`

`2000 meters - ?`

- Using proportions, we can create the following equation:

`2000 * 94 = 500 * x`

`(2000 * 94) / 500 = x`

`376 = x`

- John should do 2000 meters in 376 seconds, which is 6 minutes and 16 seconds.
