Pie Filling Calculator
Apple pie fruit and sugar for pies.
What it does
Pie filling scales by dish area: a 9 in base of 6 cups apples with 12 tbsp sugar, times pies, times the square of size ratio. This page runs that area math in cups or grams.
The default is one 9 in pie. Fruit is 6 cups with 12 tbsp sugar. Metric converts the dish to 23 cm and gives 668 g apples with 152 g sugar, a touch above the exact 9 in through rounding.
Area rules because filling fills volume. A 10 in dish holds about 23% more than a 9 in, while deep dishes and mounded tops add past flat math. Tart Granny Smiths want extra sugar beside the base.
Fruit math stops at the crust. Spice, butter dots, and thickeners follow taste and juice, with flour or tapioca per the recipe rather than this page.
How to use
- Pick imperial or metric first.
- Enter pie count.
- Enter dish size.
- Read fruit first, then sugar.
- Taste tart fruit before sealing.
Formula
- pies
- Pie count.
- size
- Pie dish diameter.
Nine inch fruit pies take about 6 cups sliced apples with 12 tbsp sugar as the base; area scales other sizes since filling fills volume across the dish. Metric weighs cups at 110 g fruit and 12.5 g sugar per tbsp. Tart fruit, deep dishes, and sweet teeth adjust up.
Worked example
Example: one apple pie
One 9 in pie (metric 23 cm).
- Scale: (9/9)^2 x 1 = 1.
- Fruit: 1 x 6 = 6 cups.
- Sugar: 1 x 12 = 12 tbsp.
- Metric: 23 cm gives 668 g apples.
- Metric sugar: 152 g.
- Tool shows 6 cups imperial.
Reference table
| Pies | Apples | Sugar |
|---|---|---|
| 0.5 | 3 cups | 6 tbsp |
| 1 | 6 cups | 12 tbsp |
| 2 | 12 cups | 24 tbsp |
| 3 | 18 cups | 36 tbsp |
| 4 | 24 cups | 48 tbsp |
Limits
- Apple base. Berries and stone fruit differ.
- Area scaling only. Deep dishes extra.
- Cup weights are averages.
- Spice and thickener excluded.
Common mistakes
- Scaling filling linearly with diameter.
- Using cups for sugar without tasting tart fruit.
- Forgetting deep dish extra.
- Mixing pie count with slice count.
- Sealing before tasting.

Two 9 in pies?
12 cups apples, 24 tbsp sugar.
Half of a 9 in pie?
3 cups apples, 6 tbsp sugar (half of base).
Questions
How many apples?
Six cups per 9 in pie scaled by area. Here 6 cups.
How much sugar?
Twelve tbsp per 9 in pie. Here 12 tbsp.
What is that in metric?
668 g apples with 152 g sugar.
Cup weights?
Six cups sliced is near 660 g; sugar 12 tbsp near 150 g.
Adjustments?
Tart fruit and deep dishes need more sugar and fruit.
Spice included?
No. Spice, butter, and thickener sit outside fruit math.
