Joule is the metric system unit to measure the energy in food, however we still see calories being used everywhere, specially advertising and fitness influencers. Let’s stop this nonsense.

    But calories are metric!

    " the heat energy needed to raise the temperature of 1 gram of water by 1 °C "

      From Wikipedia:

      However, the calorie is not part of the International System of Units (SI), and is regarded as obsolete,[2] having been replaced by the SI derived unit of energy, the joule (J),[9] or the kilojoule (kJ) for 1000 joules.

        Calories are CGS units, which is a metric system.

        What you want to argue is that they are not SI units.

        Metric ≠ SI

            No, it doesn’t

            relevant citation, highlighting by me:

            The centimetre–gram–second system of units (CGS or cgs) is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time.

        i do like kWh (1000 Watt * 1 hour) even though it’s not metric. because it’s useful in everyday life.
