You can't compare or convert that. psi is a unit of pressure; joule is a unit of energy.
1 litre diesel in joules
The energy content of steam at a given pressure, such as 150 psi, depends on the specific volume and temperature of the steam. To determine the number of joules, you would need more specific information about the steam properties.
A petajoule is 1015 joules (Quadrillion joules)
There are 56,000 joules in 56 kilojoules. This is because there are 1,000 joules in a kilojoule.
