About Converting Attomoles to Rontomoles
Attomole and Rontomole 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: Attomole is 1e-18 mole units, and rontomole is 1e-27 mole units.
Formula
rontomoles = attomoles × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 attomole equals 1e-18 base units, and 1 rontomole equals 1e-27 base units, so dividing one by the other gives the direct attomole-to-rontomole factor of 1000000000.
Simple example
1 amol × 1000000000 = 1,000,000,000 rmol
1 attomole = 1,000,000,000 rontomoles.
Real-world example
100 amol × 1000000000 = 100,000,000,000 rmol
100 attomoles = 100,000,000,000 rontomoles.

Reverse conversion: Rontomole to Attomole
1 rmol × 1e-9 = 1e-9 amol
1 rontomole = 1e-9 attomoles.
attomoles = rontomoles × 1e-9

Frequently asked questions
How many rontomoles are in 1 attomole?
1 attomole equals 1,000,000,000 rontomoles, using the exact defined conversion factor rather than an estimate.
How do I convert attomole to rontomole?
Multiply the attomole value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert rontomole back to attomole?
Use the reverse factor: 1 rontomole equals 1e-9 attomoles. You can also use the swap control in the converter above to flip the direction instantly.
What is a attomole?
Attomole (amol) is a unit of chemistry.
What is a rontomole?
Rontomole (rmol) is a unit of chemistry.
Is the attomole to rontomole conversion exact?
Yes. Both attomole and rontomole are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 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.
