Ingredient rounding
Quick answer: When scaling or converting, CookBook cleans up awkward numbers so you see kitchen-friendly amounts like 1 ⅔ cups or 2.25 kg instead of 1.59 cups or 2.247 kg. Toggle rounding in Side menu ☰ → Settings → Conversions → Rounding. Choose Rounded for tidy values or Accurate for raw decimals.
Why rounding exists
Changing units or servings often produces messy figures:
1.5 metric cups → 1.59 US cups → 1.32 imperial cups
Those amounts aren’t helpful at the stove, so CookBook nudges them to sensible fractions or neat decimals.
How CookBook rounds
Unit group | Rounding rule |
|---|---|
Cups, tsp, tbsp, fl oz, pint, ounces, dl, cl, pound | Rounded to the nearest amount below. |
ml, grams | Shown as whole numbers (no decimals like 32.7 g) |
Litres, kg, quart, stone | Rounded to the nearest 0.05 (e.g., 2.24 kg → 2.25 kg) |
Gallons | Rounded to the nearest 0.025 |
The goal is a number you can measure without a scientific beaker.
⅛ (0.125) | ¼ (0.25) | ⅓ (0.33) | ½ (0.50) | ⅔ (0.66) | ¾ (0.75) | ⅞ (0.875) |
