Kitchen Unit Conversion Chart: Cups, Tablespoons, Grams, ML
The #1 reason recipes fail: unit confusion. Here's the definitive kitchen conversion guide — cups to grams, tablespoons to ml, Fahrenheit to Celsius, and more.
The Problem: One Cup of Flour Can Be 120g or 180g
The biggest kitchen conversion trap: a 'cup' of flour varies by up to 50% depending on how you scoop it. Professional bakers use grams. Home cooks use cups. The result? Inconsistent results every time.Essential Kitchen Conversions

Frequently Asked Questions
How many grams in a cup of flour?
120 grams when properly measured (spooned and leveled). If you scoop directly from the bag, it can be 150-180g. This is why professional recipes use weight, not volume.
How do I convert Fahrenheit to Celsius?
Subtract 32, then multiply by 5/9. Quick shortcut: subtract 30, then halve it. 350°F → 350-32=318 → 318×5/9=175°C.
Why do European and American recipes differ?
European recipes use weight (grams), American recipes use volume (cups). Weight is more accurate. When converting, use a kitchen scale for best results.
