About Converting Ounces per Milliliter to Grams per Milliliter
Ounce per Milliliter and Gram per Milliliter 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 milliliter = ounces per milliliter × 28.349523125
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per milliliter equals 28349.523125 base units, and 1 gram per milliliter equals 1000 base units, so dividing one by the other gives the direct ounce per milliliter-to-gram per milliliter factor of 28.349523125.
Simple example
1 oz/mL × 28.34952313 = 28.34952313 g/mL
1 ounce per milliliter = 28.34952313 grams per milliliter.
Real-world example
100 oz/mL × 28.34952313 = 2,834.952313 g/mL
100 ounces per milliliter = 2,834.952313 grams per milliliter.

Frequently asked questions
How many grams per milliliter are in 1 ounce per milliliter?
1 ounce per milliliter equals 28.34952313 grams per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per milliliter to gram per milliliter?
Multiply the ounce per milliliter value by 28.34952313. The converter above does this instantly to whatever precision you set.
How do I convert gram per milliliter back to ounce per milliliter?
Use the reverse factor: 1 gram per milliliter equals 0.035273962 ounces per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per milliliter?
Ounce per Milliliter (oz/mL) is a unit of chemistry.
What is a gram per milliliter?
Gram per Milliliter (g/mL) measures density. Numerically identical to grams per cubic centimeter and to kilograms per liter, since one milliliter equals one cubic centimeter exactly. It is classified as a metric derived density unit.
Is the ounce per milliliter to gram per milliliter conversion exact?
Yes. Numerically identical to grams per cubic centimeter and to kilograms per liter, since one milliliter equals one cubic centimeter exactly. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
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.
