=== When energy values are low (1-10 Kcal) ===

When energy values are low, there are often matching issues between the energy in Kcal and KJ. This often because producers are rounding the values.

'''Solution or workaround:'''

Eg.

* https://world.openfoodfacts.org/product/3502110008459: In this example, 1 Kcal (rounded) => 6 KJ. Because 6 / 4.2 = '''1.428''', the producer is probably '''rounding 1.42 to 1'''.

'''Solution or workaround''': use the values per serving if the serving is higher than 100g/100ml.
