In basic terms, the average cup of black tea contains about half the caffeine found in a cup of coffee. A standard(8-ounce) cup of coffee contains about 80-100 mg(milligrams) of caffeine whereas a standard cup of black tea should be about 40 mg of caffeine. It should also be noted that black tea contains the most caffeine of all types of tea, and even then does it still have about half as much caffeine as coffee, which certainly says a lot about the caffeine content in coffee verses tea.

In case anyone reading this is ever genuinely interested, there is a lot of misinformation out there about tea and caffeine.
First, there is no such thing as a 'standard' cup of tea, so there is no such thing as a standard number for caffeine content. Also many of the numbers out there seem to quantify caffiene content of dry tea as opposed to brewed liquid, and fail to take into account size of leaf, Assamica vs Sinensis, and brewing method. Actual content could range from 10 to 100 mg in a serving.
Standard dogma is that black tea has higher caffeine content than green, but I can say from over a decade of experience that brewed 'liquor' of a fresh Japanese Matcha, Gyokuro or Sencha will give you more of a buzz than the equivalent weight of most if not all black tea's. Those and high surface area (BOP type) Assams and Ceylons seems, to me at least, to yield highest levels of caffeine. But never with the jittery results of drinking overly much coffee.
