1 1/2 cups flour or Β½ tsp salt or 0.33 cup sugar
π Common Cooking Scale Factors
- Double recipe β Multiply ingredients by 2
- Half recipe β Multiply ingredients by 0.5
- Triple recipe β Multiply by 3
- One and a half β Multiply by 1.5
- Convert 1/3 tsp β β 0.33 tsp (or a heaping 1/4 tsp)
- 0.66 tsp β 2/3 tsp β Can be measured as 1/2 + 1/8 tsp
π§ Always round spice and seasoning measurements with care when scaling!

π Example of How It Works
π Example 1: Doubling a recipe (from 2 to 4 servings)
Input Ingredients:
1/3 tsp salt
1 cup rice
1.5 cups water
Scaling Factor:4 Γ· 2 = 2
Result:
0.66 tsp salt
2 cups rice
3 cups water
π Example 2: Scaling down (from 8 to 2 servings)
Input:
1 tbsp olive oil
2 cloves garlic
1 Β½ cups spinach
Scaling Factor:2 Γ· 8 = 0.25
Result:
0.25 tbsp olive oil
0.5 cloves garlic
0.38 cups spinach
π§ The calculator intelligently handles fractional inputs like 1 1/2
or Β½
, and returns clean decimal results.
π How the Scaling Formula Works
The basic formula used for every ingredient:
New Quantity = Original Quantity Γ (Desired Servings Γ· Original Servings)
- If you’re doubling the recipe: factor = 2
- If you’re halving the recipe: factor = 0.5
- If you’re tripling: factor = 3
This ensures every ingredient is scaled consistently.
π§ Common Scaling Ratios in Cooking
Original Servings | Desired Servings | Scale Factor |
---|---|---|
2 | 4 | 2x |
4 | 2 | 0.5x |
6 | 9 | 1.5x |
3 | 1 | 0.33x |
Helpful conversions:
1/3 tsp β 0.33 tsp
2/3 tsp β 0.66 tsp
1 1/2 cups = 1.5 cups
Β½ tsp = 0.5 tsp

πββοΈ Frequently Asked Questions (FAQs)
1. Can I enter ingredients using fractions like 1/3 or Β½?
Yes! The calculator supports regular fractions (1/3
, 1 1/2
) and special characters like Β½
, ΒΌ
, ΒΎ
.
2. Will this calculator round decimals to friendly values?
Yes. Quantities are rounded to two decimal places (e.g., 0.66 = 2/3 tsp) for easier measurement. You can round manually when needed.
3. Can I scale recipes with grams or ounces?
Absolutely. As long as you keep the unit in the ingredient line (e.g., “200 grams flour”), it will scale correctly.
4. What if I enter “1 clove garlic”? Will it work?
Yes. Ingredients without numeric values will stay as-is. If you enter “1 clove garlic”, it will scale based on servings. You may get “0.5 clove garlic”, which is common in recipe scaling.
5. Can I use this on my phone while cooking?
Definitely. The calculator is optimized for mobile use so you can scale recipes directly from your phone or tablet in the kitchen.
