Formula Used

The baby clothes size calculator uses a combination of weight and height measurements to determine the appropriate size. The formula takes into account the following factors:

Baby's weight (in pounds or kilograms)
Baby's height (in inches or centimeters)
Baby's age group (newborn, infant, toddler)

// Convert weight to standard units if needed if (weightUnit === 'kg') { weight = weight * 2.20462; // Convert kg to pounds } // Convert height to standard units if needed if (heightUnit === 'cm') { height = height * 0.393701; // Convert cm to inches } // Calculate size based on age group if (ageGroup === 'newborn') { if (weight < 8) { size = '0-3 months'; } else if (weight < 12) { size = '3-6 months'; } else { size = '6-9 months'; } } else if (ageGroup === 'infant') { if (height < 22) { size = '9-12 months'; } else if (height < 24) { size = '12-18 months'; } else { size = '18-24 months'; } } else if (ageGroup === 'toddler') { if (height < 28) { size = '2T'; } else if (height < 32) { size = '3T'; } else { size = '4T'; } }

The calculator uses these measurements to determine the most appropriate baby clothes size based on standard sizing charts. The results are displayed in the result panel.
