BMI Calculator — fast, clean Body Mass Index with categories

EasiestConverter’s BMI calculator gives you a quick Body Mass Index using your weight and height, with automatic unit handling for kg/lbs and m/cm/ft. Results are presented in a clear line you can copy, along with an easy category tag (Underweight, Normal weight, Overweight, Obese) to help you interpret the number at a glance.

The interface follows our premium layout: keyboard-friendly inputs, sensible precision, and a one-tap copy button for sharing results in notes, chats, or check-ins. Optional age and sex fields can be added to your result context, while staying focused on the core calculation many wellness apps and guidelines use.

Keep in mind this BMI calculator is a general screening tool, not a diagnosis. Body composition, athletic build, and other factors can influence how your number should be interpreted. Use the value as a starting point for conversations about goals, training, or lifestyle changes.

• Switch units instantly (kg ⇄ lbs, m/cm ⇄ ft) to match your measurements.
• Use the copy button 📋 to save a clean “BMI + category” line for tracking.
• For kids, athletes, or medical questions, consult professional guidance beyond BMI alone.
