Explanation: The body fat percentage is converted to a decimal (divided by 100) and then multiplied by total body weight to get the actual fat mass.
Details: Knowing your total body fat in kilograms helps in setting realistic fitness goals, tracking fat loss progress, and understanding body composition beyond just weight.
Tips: Enter your body fat percentage (typically measured through calipers, DEXA scans, or bioelectrical impedance) and your current weight in kilograms. Both values must be > 0.
Q1: How accurate is this calculation?
A: The math is precise, but accuracy depends on how accurately your body fat percentage was measured.
Q2: What's a healthy body fat percentage?
A: For men: 6-24%, Women: 16-30%, but this varies by age and fitness level.
Q3: Can I use pounds instead of kilograms?
A: Convert pounds to kg first (1 kg = 2.2 lbs) for accurate results.
Q4: Why track fat mass instead of just weight?
A: Tracking fat mass helps distinguish between fat loss and muscle/water changes.
Q5: How often should I measure my body fat?
A: Every 2-4 weeks, as body fat changes more slowly than total weight.
