Calculating fluid syns - help

[Kron]

Hi
I have bought some syrup but not sure how to calculate syns as online uses weight.
Is it right 20 cals = 1 syn?

Actual nutrition is
52 cals per serving = 15 ml or 1/2 fl oz
Carbs = 12 g and 4% daily value
Everything else is zero

If this works out to be 3 syns I will be a happy bunny
