CM ↔ PM
Convert centimeters (cm) to picometers (pm) - and picometers to centimeters - quickly, accurately, and for free.
How the CM ↔ Picometer (pm) Converter Works
Choose the direction (CM → pm or pm → CM), enter a value, and the converter calculates the result instantly.
The conversion follows standard SI relationships, so you can use it confidently for schoolwork and quick unit checks.
- CM → pm: pm = cm × 10^10
- pm → CM: cm = pm ÷ 10^10
- Comma or dot: Enter numbers like 2.5 or 2,5.

Why Convert cm and Picometers?
Centimeters are common in everyday measurement, while picometers are used when describing extremely small distances.
This converter helps you avoid mistakes with powers of ten and quickly switch between practical and scientific units.
- Physics & chemistry: Useful for very small length scales.
- Homework: Fast unit checks during problem solving.
- Powers of ten: Reduces errors in 10^x conversions.
FAQ
How do you convert cm to picometers (pm)?
Multiply by 10^10: pm = cm × 10^10. Since 1 cm equals 10,000,000,000 pm, centimeter values become very large in picometers.
How do you convert picometers (pm) to cm?
Divide by 10^10: cm = pm ÷ 10^10.
When are picometers used?
Picometers are used for extremely small lengths, often in physics and chemistry (for example, atomic-scale distances).
