In chemistry and physics:
- Speed, being the distance covered per unit time, e.g. miles per hour and meters per second
-
- Acceleration, the rate of change in speed, or the change in speed per unit time
- Radioactive decay, the amount of radioactive material in which one nucleus decays per second, measured in Becquerels
- Reaction rate, the speed at which chemical reactions occur
- Volumetric flow rate, the volume of fluid which passes through a given surface per unit time, e.g. cubic meters per second
In computing:
- Bit rate, the number of bits that are conveyed or processed by a computer per unit of time
- Symbol rate, the number of symbol changes (signalling events) made to the transmission medium per second
- Sampling rate, the number of samples (signal measurements) per second
In finance:
- Interest rate, the price a borrower pays for the use of money they do not own, usually expressed as a percentage rate over the period of one year; see also for related rates
- Exchange rate, how much one currency is worth in terms of the other

- Rate of return, the ratio of money gained or lost on an investment relative to the amount of money invested
- Tax rate, the tax amount divided by the taxable income
Miscellaneous definitions:
- Rate of reinforcement, number of reinforcements per time, usually per minute
- Heart rate, usually measured in beats per minute

Famous quotes containing the words terms, based and/or rates:
“It must be a peace without victory.... Victory would mean peace forced upon the losers, a victor’s terms imposed upon the vanquished. It would be accepted in humiliation, under duress, at an intolerable sacrifice, and would leave a sting, a resentment, a bitter memory upon which the terms of peace would rest, not permanently, but only as upon quicksand.”
—Woodrow Wilson (1856–1924)
“Language makes it possible for a child to incorporate his parents’ verbal prohibitions, to make them part of himself....We don’t speak of a conscience yet in the child who is just acquiring language, but we can see very clearly how language plays an indispensable role in the formation of conscience. In fact, the moral achievement of man, the whole complex of factors that go into the organization of conscience is very largely based upon language.”
—Selma H. Fraiberg (20th century)
“One of the most important findings to come out of our research is that being where you want to be is good for you. We found a very strong correlation between preferring the role you are in and well-being. The homemaker who is at home because she likes that “job,” because it meets her own desires and needs, tends to feel good about her life. The woman at work who wants to be there also rates high in well-being.”
—Grace Baruch (20th century)
