How to calculate Water Intake manually
In this section we will see how to calculate the water intake manually using a formula, then we will present an example.
Let's suppose that:
- WI is the water intake (ounce)
- BW is the Body Weight (lbs)
- DW is the Duration of workout (min/day)
To calculate the water intake you can use the formula below:
WI = BW * 2 / 3 + DW / 30 * 12
Let's suppose that your body weight is 80 kg and the Duration of the workout is 1 hour per day so 60 min/day.
Before we use the formula we should convert the body weight to lbs, so 80 kg = 80 * 2.20462262 lbs = 176.3698 lbs.
Your water intake will be:
WI = 176.3698 * 2 / 3 + 60 / 30 * 12 = 141.58 ounces
Now we can convert the WI to liters, WI = 141.58 * 0.0295735 liters = 4.19 liters
