Quick question for anyone familiar with energy drink caffeine content: could someone tell me exactly how many grams of caffeine are in a standard can of Red Bull? I'm preparing a comparison and I need an accurate figure in grams rather than milligrams.

If you know the typical amount for the standard 250 ml (8.4 fl oz) can, and whether that changes for different variants (for example, Diet/Sugar-Free or regional formulas), please reply with the specific number and, if possible, a source or brief note on how you converted units.

Thanks — I appreciate a concise answer that states the exact amount in grams (and the original value in mg if available) so I can cite it correctly.
