Erg Calculator – Accurate Rowing Data

This tool calculates how many calories you burn while rowing on an ergometer.


The erg calculator above computes the kinetic energy of an object in ergs. To use the calculator:

  • Enter the mass of the object in grams.
  • Enter the velocity of the object in meters per second.
  • Click on the ‘Calculate’ button to obtain the result in ergs.

How it Works

The calculator uses the formula for kinetic energy:

Energy (erg) = 0.5 * mass (grams) * velocity^2 (m/s) * 1e7

This formula calculates the kinetic energy of an object and converts it to ergs, a unit of energy used in the centimetre-gram-second (CGS) system of units, where 1 erg = 1 g*(cm/s)^2.


  • The calculator assumes non-relativistic speeds (speeds much less than the speed of light).
  • The mass must be entered in grams and the velocity in meters per second.
  • The precision of the result is limited to two decimal places.

Use Cases for This Calculator

Calculate Calories Burned

Enter your rowing time and intensity to calculate the calories you burned during your workout. Get a precise estimation to track your progress and set new fitness goals.
