A strong coffee runs 300–600 PPM caffeine; energy drinks about 320. Enter your beverage volume and target PPM to get the milligrams — useful for product formulation.
How to use this calculator
- Enter beverage volume.
- Enter target caffeine PPM.
- Get mg of caffeine.
The formula
mg = PPM × liters (since 1 PPM = 1 mg/L).
What the inputs mean
The target is the concentration you want, in PPM. The volume is how much liquid you are treating. The result tells you exactly how much caffeine to add.
Worked example
250 mL energy drink at 320 PPM → 80 mg caffeine.
