Here in this post, we will convert * L atm to Joule*. L atm is also known as Litre Atmosphere.

## L atm to Joule

**L atm** is the product of 2 units and these 2 units are Litre (unit of volume) and Atmospheric pressure (or atmosphere which is a unit of pressure).

L atm, hence, is the product of volume and pressure and dimensionally represents work done or energy.

Now, let’s *convert L atm to its SI counterpart, i.e., Joule*.

1 Litre = 1000 mL = 1000 cm^{3} = (1000)/10^{6} m^{3} = 10^{-3} m^{3}

1 atm = 101.3 KPa = 101.3 x 10^{3} Pa (approx)

**Hence, 1 L atm = 1 Litre x 1 atm = 10 ^{-3} m^{3} x 101.3 x 10^{3} Pa = 101.3 Joule (approx)**

Here we are adding a few relevant unit conversions for quick reference.

## 1 atm or atmospheric pressure to Pascal

1 atm = 1 bar (approx)= 76.0 cm of mercury (cm Hg) = 760 mm of mercury (mm Hg) = 760 torr.

Again, **1 atm = 101.325 kPa = 101 x 10 ^{3} Pa**

## 1 Litre to m^{3} | 1 Litre to cubic meter | 1 Litre to meter cube

1 Litre = 1000 mL = 1000 cm^{3} = (1000)/10^{6} m^{3} = 10^{-3} m^{3}

## 1 millilitre to cm^{3}

1 Cubic centimeter (cm^{3}) is equal to 1 milliliter (mL)

or, 1 milliliter (mL) = 1 Cubic centimeter (cm^{3})
