频率是每单位时间重复事件的发生数量。它是在赫兹（Hz）中测量的。
1 dec = 10 cps
1 cps = 0.1 dec
例子:
将15 十年转换为每秒循环：
15 dec = 150 cps
| 十年 | 每秒循环 |
|---|---|
| 0.01 dec | 0.1 cps |
| 0.1 dec | 1 cps |
| 1 dec | 10 cps |
| 2 dec | 20 cps |
| 3 dec | 30 cps |
| 5 dec | 50 cps |
| 10 dec | 100 cps |
| 20 dec | 200 cps |
| 30 dec | 300 cps |
| 40 dec | 400 cps |
| 50 dec | 500 cps |
| 60 dec | 600 cps |
| 70 dec | 700 cps |
| 80 dec | 800 cps |
| 90 dec | 900 cps |
| 100 dec | 1,000 cps |
| 250 dec | 2,500 cps |
| 500 dec | 5,000 cps |
| 750 dec | 7,500 cps |
| 1000 dec | 10,000 cps |
| 10000 dec | 100,000 cps |
| 100000 dec | 1,000,000 cps |
