A cup of instant coffee contains about 40 - 120 mg caffeine. A cup is usually understood to contain 150 ml (5 oz in the United States), but the range of measurements is so wide that, for most individuals, it is inaccurate to use these figures as a basis for calculating the exact amount of caffeine consumed in a day.
The caffeine content of an average 5 ounce cup of brewed coffee can vary from 50 to 120mg. (an 8 ounce cup has between 80mg and 135mg). Espresso contains about 100mg of caffeine per 2 ounce cup. An average cup of espresso has about 2 to 3 times as much caffeine as an average cup of instant coffee. An average 5 ounce cup of black tea contains about 30-60mg. Instant tea contains about 12 - 28mg caffeine.
