-
- 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

Famous quotes containing the words terms, based and/or rates:
“The only freedom I care about is the freedom to do right; the freedom to do wrong I am ready to part with on the cheapest terms to anyone who will take it of me.”
—Thomas Henry Huxley (1825–95)
“A woman does not have to make decisions based on the need to survive. She can cut through issues, call shots as she sees them.... Many bad decisions are made by men in government because it is good for them personally to make bad public decisions.”
—Dianne Feinstein (b. 1933)
“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)
