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 = 1.0000e-5 MHz
1 MHz = 100,000 dec
例子:
将15 十年转换为兆赫：
15 dec = 0 MHz
| 十年 | 兆赫 |
|---|---|
| 0.01 dec | 1.0000e-7 MHz |
| 0.1 dec | 1.0000e-6 MHz |
| 1 dec | 1.0000e-5 MHz |
| 2 dec | 2.0000e-5 MHz |
| 3 dec | 3.0000e-5 MHz |
| 5 dec | 5.0000e-5 MHz |
| 10 dec | 0 MHz |
| 20 dec | 0 MHz |
| 30 dec | 0 MHz |
| 40 dec | 0 MHz |
| 50 dec | 0.001 MHz |
| 60 dec | 0.001 MHz |
| 70 dec | 0.001 MHz |
| 80 dec | 0.001 MHz |
| 90 dec | 0.001 MHz |
| 100 dec | 0.001 MHz |
| 250 dec | 0.003 MHz |
| 500 dec | 0.005 MHz |
| 750 dec | 0.008 MHz |
| 1000 dec | 0.01 MHz |
| 10000 dec | 0.1 MHz |
| 100000 dec | 1 MHz |
