Context values
Some unit families need one extra value for a physically accurate result.
Rontonewton is 1e-27 newton units.
Result = input x 1e-5 / 1e-27.
Force uses the newton as the base unit.

About Converting Dynes to Rontonewtons
Dyne and Rontonewton both measure force, and the conversion matters whenever an SI-trained engineer needs to compare notes with a US-trained one, or vice versa. Specifically: A dyne is a CGS force unit, and rontonewton is 1e-27 newton units.
Formula
rontonewtons = dynes × 1e+22
This factor comes from each unit's defined relationship to the category's base unit: 1 dyne equals 0.00001 base units, and 1 rontonewton equals 1e-27 base units, so dividing one by the other gives the direct dyne-to-rontonewton factor of 1e+22.
Simple example
1 dyn × 1e+22 = 1e+22 rN
1 dyne = 1e+22 rontonewtons.
Real-world example
10 dyn × 1e+22 = 1e+23 rN
10 dynes = 1e+23 rontonewtons.
