Frequently Asked Questions

Why is weighing ingredients better than using cups?

Cups can vary by 20-30% depending on how you scoop and pack the ingredient. A kitchen scale gives consistent, precise measurements every time, leading to more reliable baking results.

Are these conversions exact?

These are widely accepted approximations. Actual weight varies slightly based on humidity, how tightly packed the ingredient is, and the specific product. For the most precise baking, always weigh your ingredients.
