A daily and weekly estimate, based on your body and lifestyle.
Frequently asked questions
Is 2 litres a day enough water?
It depends on your weight, activity level and climate. The common "8 glasses / 2 litres" rule is a rough average. A 90 kg athlete training in Eket heat needs significantly more. Use this calculator for a figure based on your body.
How many bottles of water should I drink per day?
For most Nigerian adults: 4–8 bottles of 50cl Kayora per day, depending on weight and activity. Our calculator gives you a personalised figure.
Does hot weather increase your water needs?
Yes. Hot and humid climates like Akwa Ibom increase daily water needs by about 15% compared to cool, air-conditioned environments. The calculator accounts for this with a climate multiplier.
How many cases of water do I need per week?
Divide your weekly bottle count by 12 (bottles per case). The calculator shows this directly as "weekly packs."
