About Converting Rontomoles to Nanomoles
Rontomole and Nanomole both measure mass concentration — how much of a substance is dissolved or dispersed in a given volume — a core calculation for preparing lab solutions, checking water quality against a regulatory limit, or formulating a pharmaceutical dose. Specifically: Rontomole is 1e-27 mole units, and nanomole is 1e-9 mole units.
Formula
nanomoles = rontomoles × 1e-18
This factor comes from each unit's defined relationship to the category's base unit: 1 rontomole equals 1e-27 base units, and 1 nanomole equals 1e-9 base units, so dividing one by the other gives the direct rontomole-to-nanomole factor of 1e-18.
Simple example
1 rmol × 1e-18 = 1e-18 nmol
1 rontomole = 1e-18 nanomoles.
Real-world example
100 rmol × 1e-18 = 1e-16 nmol
100 rontomoles = 1e-16 nanomoles.

Reverse conversion: Nanomole to Rontomole
1e-18 nmol × 1e+18 = 1 rmol
1e-18 nanomoles = 1 rontomoles.
rontomoles = nanomoles × 1e+18

Frequently asked questions
How many nanomoles are in 1 rontomole?
1 rontomole equals 1e-18 nanomoles, using the exact defined conversion factor rather than an estimate.
How do I convert rontomole to nanomole?
Multiply the rontomole value by 1e-18. The converter above does this instantly to whatever precision you set.
How do I convert nanomole back to rontomole?
Use the reverse factor: 1 nanomole equals 1e+18 rontomoles. You can also use the swap control in the converter above to flip the direction instantly.
What is a rontomole?
Rontomole (rmol) is a unit of chemistry.
What is a nanomole?
Nanomole (nmol) is a unit of chemistry.
Is the rontomole to nanomole conversion exact?
Yes. Both rontomole and nanomole are defined by fixed standards rather than physical artifacts, so the factor of 1e-18 used above is exact to as many digits as you choose to display.
What's the difference between mass concentration and molarity?
Mass concentration expresses how much mass of a substance is present per unit volume (for example, grams per liter). Molarity expresses the amount in moles per liter instead, which accounts for the substance's molecular weight. This category converts mass-concentration units.
