With electronics and time measurements, you will find those terms used often: milli, micro, nano, pico.

This post is a quick reference to what each of them means.

• Milli = 10^-3 = 0,001
• Micro = 10^-6 = 0,000 001
• Nano = 10^-9 = 0,000 000 001
• Pico = 10^-12 = 0,000 000 000 001

The order I used is important to remember what they mean: repeat it a few times, milli-micro-nano-pico and you’ll remember them the next time.
