So how do you convert between the most common density units? Is there some formula that you can use to make density conversion easy?

Unfortunately, no. How you go about converting density depends on which units you're working with.

Let's go over a couple of common conversions:

## Lb/Ft^{3} and Kg/m^{3}

When converting from lb/ft^{3} to kg/m^{3}, you simply have to remember this conversion factor: 16.02. We express this as:

**1 lb/ft**^{3} = 16.02 kg/m^{3}

That's roughly how many kg/m^{3} are in a single lb/ft^{3}.

### To kg/m^{3}

So if a density is written as 3 lb/ft^{3}, you multiply it by 16.02 to convert it to kg/m^{3}.

### To lb/ft^{3}

And in order to go from kg/m^{3} to lb/ft^{3}, you simply divide by 16.02.

## Kg/m^{3} to Kg/L

When converting from kg/m^{3} to kg/L, the conversion factor you must remember is 0.001. We express this as:

That is to say, 1 kg/m^{3} equals 0.001 kg/L.

### To kg/L

So if a density is written as 7 kg/m^{3}, you multiply it by 0.001 to convert it to kg/L.

### To kg/m^{3}

To go from kg/L to kg/m^{3}, you must divide your density in kg/m^{3} by 0.001. This is the equivalent of multiplying by 1,000.
