    In all cases of conversion between volume and mass, you need to know the density of the material. In the case of lpg, are you measuring the volume as a gas or a liquid, and at what conditions? Also what is the composition of your lpg?

    In the US and Canada, lpg must be >95% propane, and you can pretty well use propane data. In other countries, it is often a seasonal mix of primarily propane and butane to control the vapor pressure, and you need the mixture percentage. If measuring as a (pressurized) liquid, the volume will vary with temperature, but around 0.51 kg/L for propane, around 0.55 kg/L for propane/butane mix at room temperature. As a gas, it will vary with both temperature and pressure, at 0 C, 101.325 kPa, it will depend on composition but around 1.6 kg/m for propane, 2.5 kg/m for propane/butane mix.
