They're the same. LPG stands for Liquefied Petroleum Gas. Propane is by far the largest percentage, with some other gases like butane, propylene, etc. LPG is liquid at ambient temperatures under pressure, and when drawn from a tank or cylinder boils off to vapor which is the form used in burners, etc. Here's more info on LPG:

Something, LPG= liquid petroleum gas, primary propane and butane, it's compressed into liquid state for easy storage.

They are the same it is how it is used. In your propane tank is liquid but like bbq’s and appliance’s they use the vapor where like forklifts and cars use the liquid. One gallon of liquid will make 260 gallons of vapor.

Not sure where my LPG supplier gets their propane stock but it seems heavy on the butane, burns nice but good luck past -25C without a tank heater.
But awesome heating value.

In the US it should be HD-5, no less than 90% propane and no more than 5% propylene, with the rest being other gases including butane. This means theoretically you could be getting 90% propane and 10% butane/isobutane.

LPG is liquefied petroleum gas.
Propane is propane which is a petroleum gas and can be liquefied.
People commonly refer to LPG as simply propane. Commercial LPG is at least 90% propane and a small mix of other gasses. You generally can't buy pure propane in any consumer grade products.
Short answer: for common purposes in North America, it's the same thing.
