A grande (16 oz) Starbucks Cappuccino has 150mg of caffeine, per the Starbucks nutrition listing (menu). That works out to 9.4mg per fluid ounce and about 1.6 cups of 8 oz brewed coffee. It takes about 2.7 grandes to reach the 400mg daily amount the FDA cites for healthy adults.

The grande against the standards

|---|---|---|---|---|
| Starbucks Cappuccino (grande) | 16 oz grande | 150mg | 9.4mg | 2.7 |

How the number behaves
A cappuccino uses the same espresso build as the latte, one shot in short and tall, two in grande and venti, so the caffeine is identical to a latte at every size. The difference is texture: less steamed milk and a deep cap of foam. If a cappuccino feels stronger than a latte, that is concentration of flavor, not caffeine.
