How many newtons is one dyne?

Exactly 0.00001 newtons (1 × 10⁻⁵ N). This is an exact conversion: 1 dyn = 1 g·cm/s², 1 N = 1 kg·m/s², and since 1 kg = 1000 g and 1 m = 100 cm, 1 N = 100,000 dyn, so 1 dyn = 1/100,000 N.

A dyne (dyn) is the CGS (centimeter-gram-second) unit of force. It is defined as the force needed to accelerate a mass of 1 gram at 1 cm/s². The dyne is much smaller than a newton — it takes 100,000 dynes to equal just 1 newton.

When would I encounter dynes?

Dynes appear in older scientific literature, surface tension measurements (dyn/cm), and CGS-based engineering references. Fields like electromagnetism using Gaussian units and materials science still use CGS quantities occasionally.

Is the conversion exact or approximate?

Exact. 1 newton = 100,000 dynes with no rounding or approximation. The conversion factor is 10⁵ precisely, derived from the definitions of the base units in both systems.

Can I convert newtons back to dynes?

Yes. To convert newtons to dynes, multiply by 100,000. Use the swap button in the converter to reverse the direction instantly.
