Pressure Canner PSI by Altitude

Look up pressure by elevation in four documented canning-table patterns. Match your recipe and gauge type, with feet or meters and clear altitude boundaries.

Use this result well

Inputs that matter
Recipe pressure table, Site elevation, Elevation unit
Output to expect
Pressure in the selected table
  • Check the units and required inputs before comparing results.
  • Keep the assumptions with a copied result so you can reproduce the calculation later.

How it works

Dial-gauge patterns

The supported dial tables use 2,000 ft bands through 8,000 ft. The snap-bean example has 11/12/13/14 PSI; the peach example has 6/7/8/9 PSI.

Weighted-gauge patterns

The supported weighted tables have a band through 1,000 ft and a band above it. The snap-bean example uses 10/15 PSI; the peach example uses 5/10 PSI.

Convert elevation before looking up its band

Meters divide by exactly 0.3048 to give feet. Exact upper boundaries stay in the lower band; any higher value enters the next band. The lookup never supplies a processing time.

Elevation in ft = elevation in m / 0.3048

Example Scenarios

Select that pattern and enter 4,000 ft.

→ 15 PSI, in the band above 1,000 ft.

Select that pattern and enter exactly 4,000 ft.

→ 12 PSI. An elevation above 4,000 ft moves into the 13 PSI band.

Select the dial 6/7/8/9 PSI pattern and enter 2,500 ft.

→ 7 PSI. Keep the matching recipe’s complete process and time.

Common Mistakes to Avoid

Selecting a table by food pH alone

Match the exact gauge and pressure pattern in the tested recipe.

Adding one PSI per 2,000 ft for every canner

Weighted and dial gauges use different documented bands. Read the selected table rather than applying a universal increment.

FAQ

Use its source table directly. Do not force it into one of the four supported patterns.

No. You must supply the matching recipe table and equipment context.

An exact boundary belongs to the lower band. Any elevation above it enters the next band.

The supported dial tables stop at 8,000 ft and the tool returns an error above that. The weighted patterns use the published above-1,000-ft band.

No. Preparation, jar size, pack style, full processing time and canner operation remain part of the tested process.

About Pressure Canner PSI by Altitude

Check the altitude band without detaching pressure from its recipe table. First match the gauge type and pressure sequence in the complete tested recipe; then enter the actual site elevation.
