Electronics Basics: Milli Micro Nano Pico

Join the AI Workshop to learn more about AI and how it can be applied to web development. Next cohort February 1st, 2026

The AI-first Web Development BOOTCAMP cohort starts February 24th, 2026. 10 weeks of intensive training and hands-on projects.


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.
