About Converting Grams per Liter to Carats per Milliliter
Gram per Liter and Carat 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. Gram per Liter is most often used for water-quality and environmental testing standards.
Formula
carats per milliliter = grams per liter × 0.005
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per liter equals 1 base unit, and 1 carat per milliliter equals 200 base units, so dividing one by the other gives the direct gram per liter-to-carat per milliliter factor of 0.005.
Simple example
1 g/L × 0.005 = 0.005 ct/mL
1 gram per liter = 0.005 carats per milliliter.
Real-world example
1,000 g/L × 0.005 = 5 ct/mL
1,000 grams per liter = 5 carats per milliliter.
Conversion table
| Gram per Liter (g/L) | Carat per Milliliter (ct/mL) |
|---|---|
| 0.1 g/L | 0.0005 ct/mL |
| 1 g/L | 0.005 ct/mL |
| 10 g/L | 0.05 ct/mL |
| 100 g/L | 0.5 ct/mL |
| 1,000 g/L | 5 ct/mL |
| 10,000 g/L | 50 ct/mL |
Reverse conversion: Carat per Milliliter to Gram per Liter
0.005 ct/mL × 200 = 1 g/L
0.005 carats per milliliter = 1 grams per liter.
grams per liter = carats per milliliter × 200

Frequently asked questions
How many carats per milliliter are in 1 gram per liter?
1 gram per liter equals 0.005 carats per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per liter to carat per milliliter?
Multiply the gram per liter value by 0.005. The converter above does this instantly to whatever precision you set.
How do I convert carat per milliliter back to gram per liter?
Use the reverse factor: 1 carat per milliliter equals 200 grams per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per liter?
Gram per Liter (g/L) measures mass concentration. One gram of a substance dissolved or dispersed per liter of total solution or mixture volume. It is classified as a metric derived concentration unit.
What is a carat per milliliter?
Carat per Milliliter (ct/mL) is a unit of density.
Is the gram per liter to carat per milliliter conversion exact?
Yes. Both gram per liter and carat per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.005 used above is exact to as many digits as you choose to display.
Where is the gram per liter still used today?
Standard unit for water-quality and laboratory concentration reporting worldwide
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.
