Explanation

Formula: Calories = Watt-hours × 860.42065. Why: watt-hour units convert to energy through the exact relationship 1 Wh = 3,600 J, so the calculator normalizes through joules before applying the target scale.

Watt-hours (Wh): an electrical energy unit equal to 3,600 joules, common for batteries, devices, and utility sub-metering.

Calories (cal): a small thermal energy unit with a fixed joule equivalent, used in chemistry and heat calculations.

This route is useful when translating electrical energy values between joules, watt-hours, and kilowatt-hours for batteries, storage, and utility consumption comparisons.

This conversion is purely multiplicative because both units reduce through joules using fixed energy definitions with no offset.
