Frequently Asked Questions
What is BMI?
BMI (Body Mass Index) measures body fat based on height and weight using the formula: weight(kg) / height(m)². Toolscal's BMI Calculator categorizes results as underweight (<18.5), normal (18.5-24.9), overweight (25-29.9), or obese (30+).
Is BMI accurate?
BMI is a useful screening tool but doesn't measure muscle mass or body composition. Athletes may have high BMI from muscle, not fat. Toolscal provides BMI as one indicator; consult healthcare providers for complete assessment.

A healthy BMI ranges from 18.5 to 24.9 for most adults. Toolscal shows your exact category and healthy weight range for your height. Ideal BMI varies by age and ethnicity.
