The unit of measurement varies by region: a United States tablespoon is approximately 14.8 ml (0.50 US fl oz), a United Kingdom and Canadian tablespoon is exactly 15 ml (0.51 US fl oz),[2] and an Australian tablespoon is 20 ml (0.68 US fl oz).[3]

We don't have any option to relate the unit of measurement to a locality. The difference between the US and UK/Canadian tablespoon might be negligible, but the Australian tablespoon is so far off, that nutrition value (if defined in tablespoons) would be massively skewed for usage in comparisons.

One option might be to ask users to use "US Tbsp" or "AUS Tbsp", but as we actually want users to add this information as it was printed on the packaging, that would be different to most other fields.
