About Converting Femtomoles to Gigamoles
Femtomole and Gigamole 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: Femtomole is 1e-15 mole units, and gigamole is 1000000000 mole units.
Formula
gigamoles = femtomoles × 1e-24
This factor comes from each unit's defined relationship to the category's base unit: 1 femtomole equals 1e-15 base units, and 1 gigamole equals 1000000000 base units, so dividing one by the other gives the direct femtomole-to-gigamole factor of 1e-24.
Simple example
1 fmol × 1e-24 = 1e-24 Gmol
1 femtomole = 1e-24 gigamoles.
Real-world example
100 fmol × 1e-24 = 1e-22 Gmol
100 femtomoles = 1e-22 gigamoles.

Reverse conversion: Gigamole to Femtomole
1e-24 Gmol × 1e+24 = 1 fmol
1e-24 gigamoles = 1 femtomoles.
femtomoles = gigamoles × 1e+24

Frequently asked questions
How many gigamoles are in 1 femtomole?
1 femtomole equals 1e-24 gigamoles, using the exact defined conversion factor rather than an estimate.
How do I convert femtomole to gigamole?
Multiply the femtomole value by 1e-24. The converter above does this instantly to whatever precision you set.
How do I convert gigamole back to femtomole?
Use the reverse factor: 1 gigamole equals 1e+24 femtomoles. You can also use the swap control in the converter above to flip the direction instantly.
What is a femtomole?
Femtomole (fmol) is a unit of chemistry.
What is a gigamole?
Gigamole (Gmol) is a unit of chemistry.
Is the femtomole to gigamole conversion exact?
Yes. Both femtomole and gigamole are defined by fixed standards rather than physical artifacts, so the factor of 1e-24 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.
