Copy the exact product, flavor/version, date checked and label source.
Use mL for volume, mg for caffeine, g for sugars, and kcal for calories.
Write UNKNOWN for undisclosed caffeine. Confirm whether the total includes
guarana and other sources before adding quantities.

                                Product A         Product B
Product and label source:       __________        __________
Container volume (mL):          __________        __________
Label serving volume (mL):      __________        __________
Caffeine per label serving(mg): __________        __________
Calories per serving (kcal):    __________        __________
Total sugars per serving (g):  __________        __________
Added sugars per serving (g):  __________        __________
Volume I will drink (mL):       __________        __________

Multiplier = volume consumed / label serving volume.
Multiply each per-serving amount by that multiplier. Added sugars are part
of total sugars: never add those two lines together. If a caffeine statement
is per container, use container volume as its denominator instead.

Worked FICTIONAL example: 80 mg caffeine per 250 mL serving, with 375 mL
consumed, gives 80 x 375 / 250 = 120 mg. A 500 mL whole bottle gives 160 mg.
For concentration per 100 mL: amount / stated volume x 100.
These examples are arithmetic only, not actual product labels.
