Altitude Adjustments (pressure canning)

Here is a handy table showing the pressure required for dial and weighted pressure canning at different altitudes in feet (and metres) above sea level ...
The recipes on this website assume an altitude of 0 - 1000 feet above sea level, so adjust your pressure according to your location. You do not need to adjust the processing time, just the pressure level. I have included both altitude in feet and altitude in metres - for other Australians to find it easy to calculate too ... for example, my town in Perth, Western Australia is 57 metres above sea level. I have a dial gauge pressure canner, so I use 11 pounds pressure when pressure canning.
