A Cup of Coffee

The liquid that turns 'I can't even' into 'I am unstoppable'/Food & Drinks

A standard cup of brewed coffee is about 236 milliliters, weighs roughly 240 grams (slightly denser than water due to dissolved solids), and is served at around 67°C (340 K). It contains about 95 mg of caffeine, which provides roughly 8,400 joules of metabolic energy boost. Coffee is the world's second most traded commodity after crude oil, and about 2.25 billion cups are consumed globally every day.
