Baking Altitude Calculator — Formula
## How Altitude Affects Baking
At higher elevations, lower air pressure causes gases to expand more quickly, liquids to evaporate faster, and sugars to concentrate sooner. Adjustments are needed to compensate.
### General Rules Per 1,000 ft Above 3,500 ft
- **Temperature**: Increase by 15-25F
- **Sugar**: Decrease by 1% per 1,000 ft
- **Liquid**: Increase by 2% per 1,000 ft
- **Leavening**: Decrease by 4% per 1,000 ft

Exemplo Resolvido
Baking at 5,000 ft with recipe at 350F, 1 cup sugar, 1 cup liquid, 2 tsp baking powder.
- Altitude factor = 5000 / 1000 = 5
- Adjusted temp = 350 + 25 = 375F
- Adjusted sugar = 1 x (1 - 5 x 0.01) = 0.95 cups
- Adjusted liquid = 1 x (1 + 5 x 0.02) = 1.10 cups
- Adjusted baking powder = 2 x (1 - 5 x 0.04) = 1.60 tsp
