# Thread: What's the difference between frequency and hertz?

1. ## What's the difference between frequency and hertz? var addthis_config = {"data_track_clickback":false};

I believe frequency is the number of crests in 1 second. Hertz is a measure of frequency. 1 wave per second is equal to 1 hertz. But this just seems to me like hertz is just another name for frequency? Does hertz measure crests and troughs?

2. hertz is the unit of frequency.

3. Hertz is defined as cycles per second. HZ did not come into wide use until the 70's. Old textbooks refer to frequency as CPS cycles per second.

4. Hertz is the unit used to measure frequency.

Like kilograms is used to meaure weight.

5. Hertz is the unit of frequency. Just like metres is the unit of measurement for distance.

Hertz is not another name for frequency.

Frequency shows the number of waves (1wave = 1crest +1 trough) in one second. Hertz is just the unit to show that we're referring to frequency.

6. Hertz are units for frequency, as meters are units for length.

Units of frequency sometimes have the form seconds to the minus one power, commonly referred to as cycles per second.

1 Hertz = 1 cycle per second

7. Hertz is the unit for frequency, much like metre is a unit for measuring length.

it doesn't measure the height of the crests and troughs but does give you an indication of the number of crests and troughs in 1 second.

1 wave per second is 1 hertz (1 crest + 1 trough)
2 waves per second is 2 hertz (2 crest +2 trough)

8. Yes; one hertz is one cycle per second, so the number of cycles per second in hertz is indeed the frequency. If something operates at 1000 cycles per second, then it operates at 1 kilohertz (kHz), and that is its frequency.

9. Hertz is the unit of frequency. It is like saying pounds / Kgs is same as weight. Well in a way they are as they are units of weight. Likewise Hertz.

10. Frequency is the number of cycles per second, and Hertz is the unit of measure for frequency.

(Example. The frequency for that station is 9000 Hertz.)

Hope that helps?
