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 kHz = 100 dec
1 dec = 0.01 kHz
例子:
将15 千赫转换为十年：
15 kHz = 1,500 dec
| 千赫 | 十年 |
|---|---|
| 0.01 kHz | 1 dec |
| 0.1 kHz | 10 dec |
| 1 kHz | 100 dec |
| 2 kHz | 200 dec |
| 3 kHz | 300 dec |
| 5 kHz | 500 dec |
| 10 kHz | 1,000 dec |
| 20 kHz | 2,000 dec |
| 30 kHz | 3,000 dec |
| 40 kHz | 4,000 dec |
| 50 kHz | 5,000 dec |
| 60 kHz | 6,000 dec |
| 70 kHz | 7,000 dec |
| 80 kHz | 8,000 dec |
| 90 kHz | 9,000 dec |
| 100 kHz | 10,000 dec |
| 250 kHz | 25,000 dec |
| 500 kHz | 50,000 dec |
| 750 kHz | 75,000 dec |
| 1000 kHz | 100,000 dec |
| 10000 kHz | 1,000,000 dec |
| 100000 kHz | 10,000,000 dec |
