These calculators turn common health questions into clear numbers: how much you should eat, whether your weight is in a healthy range, how much protein and water you need, and when your baby is due. They use standard formulas and Indian guidance where it exists, such as the Asian Indian BMI cut-offs and ICMR-NIN protein advice.
Which calculator should I use?
- Weight: check your BMI, your ideal weight for your height and your body fat percentage.
- Diet: find your daily needs with the calorie calculator and BMR calculator, then split them with the macro calculator and protein calculator.
- Exercise and water: see the calories burned in walking, yoga or sports, and your daily water intake.
- Pregnancy: find your fertile days with the ovulation calculator and your delivery date with the pregnancy due date calculator.
FAQ
Are these calculators medical advice?
No. They give general estimates for healthy adults. If you are pregnant, have a health condition or take medicines, follow your doctor's advice.
Why do you use lower BMI cut-offs for Indians?
Research shows that South Asians face a higher risk of diabetes and heart disease at a lower BMI than Europeans. Indian guidelines treat a BMI of 23 or more as overweight, and our calculators show both the WHO and the Asian Indian scales.
Do you store my health details?
No. All calculations run in your browser. We do not save the numbers you type.
