About Converting Centigrams per Fluid ounce to Micrograms per Liter
Centigram per Fluid ounce and Microgram per Liter both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
micrograms per liter = centigrams per fluid ounce × 338140.227018
This factor comes from each unit's defined relationship to the category's base unit: 1 centigram per fluid ounce equals 0.338140227018 base units, and 1 microgram per liter equals 0.000001 base units, so dividing one by the other gives the direct centigram per fluid ounce-to-microgram per liter factor of 338140.227018.
Simple example
1 cg/fl oz × 338140.227 = 338,140.227 ug/L
1 centigram per fluid ounce = 338,140.227 micrograms per liter.
Real-world example
1,000 cg/fl oz × 338140.227 = 338,140,227 ug/L
1,000 centigrams per fluid ounce = 338,140,227 micrograms per liter.

Frequently asked questions
How many micrograms per liter are in 1 centigram per fluid ounce?
1 centigram per fluid ounce equals 338,140.227 micrograms per liter, using the exact defined conversion factor rather than an estimate.
How do I convert centigram per fluid ounce to microgram per liter?
Multiply the centigram per fluid ounce value by 338140.227. The converter above does this instantly to whatever precision you set.
How do I convert microgram per liter back to centigram per fluid ounce?
Use the reverse factor: 1 microgram per liter equals 0.0000029574 centigrams per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a centigram per fluid ounce?
Centigram per Fluid ounce (cg/fl oz) is a unit of density.
What is a microgram per liter?
Microgram per Liter (ug/L) is a unit of density.
Is the centigram per fluid ounce to microgram per liter conversion exact?
Yes. Both centigram per fluid ounce and microgram per liter are defined by fixed standards rather than physical artifacts, so the factor of 338140.227 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
