Adjusting for Elevatoin When Canning Food

Adjusting for Elevation When Canning Food

 

 

Adjustments must be made for different altitudes when canning food. Boiling points are different at every elevation. Water begins to boil quicker and at a lower temperature as altitude increases. These lower boiling temperatures will not kill bacteria effectively. To ensure pressure reaches the required 240 degrees F, these adjustments must be made:

 

Pounds of Pressure at: Elevation - Dial Gauge - Weighted Gauge Sea Level - 10 - 10 1,000 ft - 10 1/2 - 15 2,000 ft - 11 - 15 3,000 ft - 11 1/2 - 15 4,000 ft - 12 - 15 5,000 ft - 12 1/2 - 15 6,000 ft - 13 - 15 7,000 ft - 13 1/2 - 15 8,000 ft - 14 - 15 9,000 ft - 14 1/2 - 15 10,000 ft - 15 - 15
