The Powers in Engineering / Scientific Notation
This shows the names of the powers of ten in thousand increments (example in Hertz).
| 0.000,000,000,000,000,000,000,001 | = | 1 yHz (1 yocto Hertz) | = | 1 x 10-24 Hz |
| 0.000,000,000,000,000,000,001 | = | 1 zHz (1 zepto Hertz) | = | 1 x 10-21 Hz |
| 0.000,000,000,000,000,001 | = | 1 aHz (1 atto Hertz) | = | 1 x 10-18 Hz |
| 0.000,000,000,000,001 | = | 1 fHz (1 femto Hertz) | = | 1 x 10-15 Hz |
| 0.000,000,000,001 | = | 1 pHz (1 pico Hertz) | = | 1 x 10-12 Hz |
| 0.000,000,001 | = | 1 nHz (1 nano Hertz) | = | 1 x 10-9 Hz |
| 0.000,001 | = | 1 µHz (1 micro Hertz) | = | 1 x 10-6 Hz |
| 0.001 | = | 1 mHz (1 milli Hertz) | = | 1 x 10-3 Hz |
| 1 | = | 1 Hz (1 Hertz) | = | 1 x 100 Hz |
| 1,000 | = | 1 kHz (1 kilo Hertz) | = | 1 x 103 Hz |
| 1,000,000 | = | 1 MHz (1 Mega Hertz) | = | 1 x 106 Hz |
| 1,000,000,000 | = | 1 GHz (1 Giga Hertz) | = | 1 x 109 Hz |
| 1,000,000,000,000 | = | 1 THz (1 Tera Hertz) | = | 1 x 1012 Hz |
| 1,000,000,000,000,000 | = | 1 PHz (1 Peta Hertz) | = | 1 x 1015 Hz |
| 1,000,000,000,000,000,000 | = | 1 EHz (1 Exa Hertz) | = | 1 x 1018 Hz |
| 1,000,000,000,000,000,000,000 | = | 1 ZHz (1 Zetta Hertz) | = | 1 x 1021 Hz |
| 1,000,000,000,000,000,000,000,000 | = | 1 YHz (1 Yotta Hertz) | = | 1 x 1024 Hz |
Note: for values smaller than 1 lowercase is used, for values greater than 1 uppercase. The exception is k for kilo, 1,000 (103). K for Kilo is reserved for the value 1,024 (210), see example below.
| 20 | = | 1 | (bit) | | | 28 | = | 256 | (byte) |
| 21 | = | 2 | | | 29 | = | 512 | ||
| 22 | = | 4 | | | 210 | = | 1'024 | (1 KB) | |
| 23 | = | 8 | | | 211 | = | 2'048 | (2 KB) | |
| 24 | = | 16 | (nibble) | | | 212 | = | 4'096 | (4 KB) |
| 25 | = | 32 | | | 213 | = | 8'192 | (8 KB) | |
| 26 | = | 64 | | | 214 | = | 16'384 | (16 KB) | |
| 27 | = | 128 | | | 215 | = | 32'768 | (32 KB) |
