### TIL a Starbucks grande coffee has 320 milligrams of caffeine, over four times the amount of caffeine in a Red Bull and the Starbucks cinnamon chip scone has more calories than a McDonald's quarter pounder with 480 calories

Noticing all the numbers, I had to make mathematical sense of all of this.

Based on searching the amount of caffeine in one shot of espresso (https://www.google.com/search?q=caffeine+in+a+shot+of+espresso&ie=utf-8&oe=utf-8). I determined that:

One shot of espresso has 64 milligrams (mg) of caffeine per 1 fluid ounce (fl. oz).

That would mean that one 16 fl. oz of coffee would contain 5 shots of espresso.

``````320 mg of caffeine in one 16 fl. oz drink / 64 mg of caffeine in one shot of    espresso = 5 shots of espresso in one 16 fl. oz drink.
``````

Based on searching the amount of caffeine in one can of Red Bull: (http://www.caffeineinformer.com/caffeine-content/red-bull)

One 8.46 fl. oz of Red Bull contains 80mg of caffeine. To reach the amount of caffeine in a 16 fl. oz drink from Starbucks, you would need to consume 4 cans of Red Bull.

``````320mg in a 16 fl. oz drink at Starbucks / 80mg in an 8.46 fl. oz can of Red Bull    = 4 cans of Red Bull.
``````

In retrospect, that seems find until you understand the fact that one 8.46 fl. oz can of Red Bull contains 27 grams (g) of sugar: (http://tracker.dailyburn.com/nutrition/red_bull_red_bull_250_calories)

If you were to consume the same amount of caffeine as a 16 fl. oz Starbucks coffee, you would ingest:

``````Four 8.46 fl. oz cans of Red Bull * 27 g of sugar per can = 108 grams of sugar.
``````

If you were to order a 16 fl. oz drink from Starbucks, in this case a Caffè Latte (http://www.starbucks.com/menu/drinks/espresso/caffe-latte), you would consume only 17g or sugar. That is clearly a better option even with the higher amount of caffeine.

TL;DR:

-A Starbucks Grande 16 fl. oz drink contains 320mg of caffeine and 17g of sugar.

• A 8.46 fl. oz can of Red Bull contains 80mg of caffeine and 27g of sugar.

• You would need to consume four cans of Red Bull to reach the amount of caffeine in one Starbucks 16 fl. oz drink.

• That would result in ingesting at least 108g of sugar.

Edit: thank you to whomever pointed out the error for the amount of caffeine. I deleted that part. Otherwise everything else looks fine.
