Water Intake Calculator for Gym
Estimate how much water to drink each day using your bodyweight and a simple hydration formula for gym training.
Based on 70 kg bodyweight
Bodyweight used: 70 kg
How much water should I drink for the gym?
A simple starting estimate: bodyweight in KG x 0.033 = Litres per day. For example, someone weighing 70 kg would get a target of about 2.31 litres per day.
How is the water intake calculated?
The formula used is bodyweight in kilograms × 0.033 = estimated daily water intake in litres. This calculator converts pounds to kilograms before applying the formula.
Should I drink more water when exercising?
Exercise, sweating, heat, session length, and individual needs can increase the amount of fluid you need. Use this result as a starting estimate and drink regularly around your training.
How do I use this calculator?
Enter your bodyweight, choose kilograms or pounds, and the calculator will show an estimated daily water target in litres.
