About Converting Milligrams per Fluid ounce to Grams per Fluid ounce
Milligram per Fluid ounce and Gram per Fluid ounce 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. Both are mass concentration units.
Formula
grams per fluid ounce = milligrams per fluid ounce × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per fluid ounce equals 0.0338140227018 base units, and 1 gram per fluid ounce equals 33.8140227018 base units, so dividing one by the other gives the direct milligram per fluid ounce-to-gram per fluid ounce factor of 0.001.
Simple example
1 mg/fl oz × 0.001 = 0.001 g/fl oz
1 milligram per fluid ounce = 0.001 grams per fluid ounce.
Real-world example
100 mg/fl oz × 0.001 = 0.1 g/fl oz
100 milligrams per fluid ounce = 0.1 grams per fluid ounce.

What is a milligram per fluid ounce?
Milligram per Fluid ounce (mg/fl oz) is a unit of chemistry.
What is a gram per fluid ounce?
Gram per Fluid ounce (g/fl oz) is a unit of chemistry.
Is the milligram per fluid ounce to gram per fluid ounce conversion exact?
Yes. Both milligram per fluid ounce and gram per fluid ounce are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
