Purpose of the density unit converter
The density unit converter is an invaluable tool for quickly switching between commonly used density units. From scientific research to everyday applications, understanding density is essential. Here’s a comprehensive guide to converting and applying density units effectively using our calculator.
Units
In this converter, the units of measurement are divided into two systems: Metric and Imperial.
Metric units (Most commonly used for scientific calculations):
- Tons per cubic meter (t/m³)
- Kilograms per cubic meter (kg/m³)
- Kilograms per cubic decimeter (kg/dm³)
- Kilograms per liter (kg/L)
- Grams per liter (g/L)
- Grams per deciliter (g/dL)
- Grams per milliliter (g/mL)
- Grams per cubic centimeter (g/cm³) Most popular in scientific contexts
- Milligrams per liter (mg/L)
Imperial units (Often used in the United States):
- Ounces per cubic inch (oz/cu in)
- Pounds per cubic inch (lb/cu in)
- Pounds per cubic foot (lb/cu ft) Common in engineering in the US
- Pounds per cubic yard (lb/cu yd)
- Pounds per gallon (US) (lb/US gal)
Conversion table
Below is an extended table with additional density units to help you understand conversion factors among various common units.
| From/To | kg/m³ | g/cm³ | mg/L | lb/cu ft | lb/US gal | oz/cu in |
|---|---|---|---|---|---|---|
| 1 kg/m³ | 1 | 0.001 | 1000 | 0.06243 | 0.00835 | 0.00058 |
| 1 g/cm³ | 1000 | 1 | 1,000,000 | 62.428 | 8.345 | 0.578 |
| 1 mg/L | 0.001 | 0.000001 | 1 | 0.000062 | 0.000008 | 3.6127e-8 |
| 1 lb/cu ft | 16.018 | 0.016 | 16,018 | 1 | 0.1337 | 0.009 |
| 1 lb/US gal | 119.83 | 0.12 | 119,830 | 7.48052 | 1 | 0.00749 |
| 1 oz/cu in | 1729.99 | 1.73 | 1,729,994 | 108.0 | 14.091 | 1 |
Formula
To convert density units, we apply simple multiplication based on conversion factors.
For example, to convert kilograms per cubic meter to grams per liter (g/L), you calculate:
Because 1 kg/m³ equals 1 g/L.
Examples
Example 1: Converting g/cm³ to kg/m³
Convert 2 g/cm³ to kg/m³:
Example 2: Converting kg/m³ to lb/cu ft
Let’s convert 500 kg/m³ to lb/cu ft:
Example 3: Converting g/cm³ to lb/US gal
Convert 2 g/cm³ to lb/US gal:
Frequently asked questions
How to convert mg/L to g/L?
To convert from mg/L to g/L, multiply by 0.001. For example, 1000 mg/L becomes:
How many grams per deciliter are in 1 g/L?
1 gram per liter (g/L) equals 0.1 gram per deciliter (g/dL). This is because there are 10 deciliters in 1 liter, so the concentration in grams per deciliter will be 10 times less than in grams per liter.
What unit is best for high precision measurements?
Grams per milliliter (g/mL) or grams per cubic centimeter (g/cm³) are often used for high precision laboratory measurements due to their small-scale accuracy.

How does temperature affect density?
Density can change depending on temperature. Generally, as temperature increases, the volume of a substance increases, leading to a decrease in density. This is especially true for liquids and gases. However, for water, there is an exception in the range from 0°C to 4°C, where its density first increases before beginning to decrease.
