    About this calculator:

    • Based on thermodynamic calculations for milk (specific heat: 4.18 J/g°C, density: 1.03 g/ml)
    • Heating power calibrated from real observations: 3L from 11°C to 70°C in 16 minutes
    • Cooling uses Newton's Law of Cooling with refined constant (0.015)
    • Assumes typical kitchen heating source (500-900W range)
