What conventional oven time is equivalent to a pressure cooker time?

A general rule of thumb is that cooking in a pressure cooker takes about one-third of the time it would in a conventional oven. For example, if a dish requires 60 minutes in the oven, it would typically take about 20 minutes in a pressure cooker. However, this can vary based on the specific recipe and ingredients, so it's always best to consult a specific recipe for accurate times.
