About Converting Ronnawatts to Nanowatts
Ronnawatt and Nanowatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Ronnawatt is 1e+27 watt units, and nanowatt is 1e-9 watt units.
Formula
nanowatts = ronnawatts × 1e+36
This factor comes from each unit's defined relationship to the category's base unit: 1 ronnawatt equals 1e+27 base units, and 1 nanowatt equals 1e-9 base units, so dividing one by the other gives the direct ronnawatt-to-nanowatt factor of 1e+36.
Simple example
1 RW × 1e+36 = 1e+36 nW
1 ronnawatt = 1e+36 nanowatts.
Real-world example
100 RW × 1e+36 = 1e+38 nW
100 ronnawatts = 1e+38 nanowatts.

Reverse conversion: Nanowatt to Ronnawatt
1e+36 nW × 1e-36 = 1 RW
1e+36 nanowatts = 1 ronnawatts.
ronnawatts = nanowatts × 1e-36

Frequently asked questions
How many nanowatts are in 1 ronnawatt?
1 ronnawatt equals 1e+36 nanowatts, using the exact defined conversion factor rather than an estimate.
How do I convert ronnawatt to nanowatt?
Multiply the ronnawatt value by 1e+36. The converter above does this instantly to whatever precision you set.
How do I convert nanowatt back to ronnawatt?
Use the reverse factor: 1 nanowatt equals 1e-36 ronnawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a ronnawatt?
Ronnawatt (RW) is a unit of engineering.
What is a nanowatt?
Nanowatt (nW) is a unit of engineering.
Is the ronnawatt to nanowatt conversion exact?
Yes. Both ronnawatt and nanowatt are defined by fixed standards rather than physical artifacts, so the factor of 1e+36 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
