Celsius has more caffeine than brewed white tea on both counts: 200mg per 12 oz can against 28mg per 8 oz cup, and about 17mg per fluid ounce against 4. The serving sizes differ, so the table below shows both ways of counting.

Energy drinks and sodas list an exact number because caffeine is a measured additive; brewed drinks vary with the beans and the brew, so their figures are compiled averages. The numbers here are the standard published values for each.

The concentration gap is the striking part: Celsius packs roughly 5 times the caffeine per ounce. Sipping speed matters at that density; a 12 oz can finished in minutes hits differently than the same milligrams spread over a slow cup.
Which one should you pick?
Pick brewed white tea when you want the lighter dose or a slower ramp, and Celsius when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
