'''Points Formula in SI units:'''

p = E / 300 kJ + ms / 4 g



Where ''p'' is the (dimensionless) points value, ''E'' is the overall energy content and ''ms'' is the saturated fat content. In practice ''p'' is rounded to the nearest ½ point.

Since food labels in New Zealand specify energy content in kilojoules and saturated fat in grams, we can eliminate the units and simplify:

p = E / 300 + ms / 4

For instance 25 g of chocolate is 593 kJ and 5.8 g saturated fat, which is 3½ points.
