About Converting Grams per Fluid ounce to Kilograms per Milliliter
Gram per Fluid ounce and Kilogram per Milliliter 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
kilograms per milliliter = grams per fluid ounce × 0.0000338140227018
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per fluid ounce equals 33.8140227018 base units, and 1 kilogram per milliliter equals 1000000 base units, so dividing one by the other gives the direct gram per fluid ounce-to-kilogram per milliliter factor of 0.0000338140227018.
Simple example
1 g/fl oz × 0.0000338140227 = 0.000033814 kg/mL
1 gram per fluid ounce = 0.000033814 kilograms per milliliter.
Real-world example
1,000 g/fl oz × 0.0000338140227 = 0.0338140227 kg/mL
1,000 grams per fluid ounce = 0.0338140227 kilograms per milliliter.

Frequently asked questions
How many kilograms per milliliter are in 1 gram per fluid ounce?
1 gram per fluid ounce equals 0.000033814 kilograms per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per fluid ounce to kilogram per milliliter?
Multiply the gram per fluid ounce value by 0.0000338140227. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per milliliter back to gram per fluid ounce?
Use the reverse factor: 1 kilogram per milliliter equals 29,573.52956 grams per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per fluid ounce?
Gram per Fluid ounce (g/fl oz) is a unit of density.
What is a kilogram per milliliter?
Kilogram per Milliliter (kg/mL) is a unit of density.
Is the gram per fluid ounce to kilogram per milliliter conversion exact?
Yes. Both gram per fluid ounce and kilogram per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.0000338140227 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.
