Cups (cups)
About this calculator
Uses US customary cups (236 mL) and approximate ingredient weights. Flour packing, how you fill the cup, and brand can change the result; use a scale when precision matters.
Worked example
calculated with the default values below
Weight 250 g · Ingredient All-purpose flour Cups 2.0000 cups · Tablespoons 32.0 tbsp · Grams per cup (this ingredient) 125 g
Method and assumptions
cups = g/d; tbsp = 16g/d d is a lookup: flour 125, bread flour 127, sugar 200, brown sugar 220, butter 227, water 236, milk 244, rice 185, oats 90, cocoa 85, honey 340, salt 288; unknown ingredient defaults to 125.

Frequently asked questions
Why does a cup of flour weigh less than sugar?
The converter looks up a density per ingredient: flour is 125 g per cup, sugar 200 and honey 340, because each packs differently. So 250 g of flour is 2 cups but the same 250 g of sugar is only 1.25 cups. The grams-per-cup output shows the factor used, and tablespoons are simply the cup value times 16, so 2 cups is 32 tablespoons.
Which cup size does this converter use?
It uses a US customary cup of about 236 mL. Ingredient weights are estimates: flour packing, how you fill the cup, and brand can change them. Weigh ingredients when precision matters.

What is a complete worked example for Weight = 250 g; Ingredient = All-purpose flour?
Inputs: Weight = 250 g; Ingredient = All-purpose flour. Calculation: cups = g/d; tbsp = 16g/d. Results: Cups = 2.0000 cups; Tablespoons = 32.0 tbsp; Grams per cup (this ingredient) = 125 g.
