Cooking Altitude Adjustment Calculator
Adjust baking temperatures, times, and ingredient amounts for high altitude cooking.
Works for any elevation.
Altitude Adjustments
High altitude cooking requires adjustments because air pressure is lower at higher elevations.
What changes at high altitude:
- Water boils at a lower temperature (about 2°F / 1°C less per 1,000 ft / 300 m)
- Leavening agents (baking powder, yeast) work faster
- Liquids evaporate faster
- Sugar becomes more concentrated
General adjustments for baking above 3,500 ft (1,067 m):
| Adjustment | 3,500 ft | 5,000 ft | 7,000 ft |
|---|---|---|---|
| Oven temperature | +15°F | +25°F | +25°F |
| Sugar (per cup) | -1 tbsp | -2 tbsp | -3 tbsp |
| Liquid (per cup) | +2 tbsp | +3 tbsp | +4 tbsp |
| Baking powder | -1/8 tsp | -1/4 tsp | -1/4 tsp |
| Flour (per cup) | +1 tbsp | +2 tbsp | +3 tbsp |
Boiling point by altitude:
- Sea level: 212°F (100°C)
- 5,000 ft: 203°F (95°C)
- 7,500 ft: 198°F (92°C)
- 10,000 ft: 194°F (90°C)
Tips: Start with small adjustments and fine-tune based on results.
