Cooking Conversions Guide

Why conversions matter in cooking

Cooking is a balance of ratios. A small change in flour, sugar, or temperature can affect texture, rise, and flavor. Using accurate conversions helps you reproduce recipes consistently.

Volume vs weight

Cups measure volume while grams measure weight. The same volume of different ingredients has different weights because of density. That is why 1 cup of flour weighs much less than 1 cup of sugar.

Cups to grams formula

The formula is: grams = cups * grams per cup. The grams-per-cup value depends on the ingredient. Use a calculator that accounts for ingredient type for best results.

Oven temperature conversions

Celsius to Fahrenheit uses: F = (C * 9/5) + 32. Fahrenheit to Celsius uses: C = (F - 32) * 5/9. Most ovens are not perfectly calibrated, so treat these as approximations and adjust by experience.

Scaling recipes

If a recipe makes 4 servings and you want 6, multiply every ingredient by 1.5. The formula is: new amount = original amount * (new servings / original servings). This preserves ratios.

Worked example

A cookie recipe uses 2 cups of flour and 1 cup of sugar for 4 servings. For 8 servings, flour becomes 4 cups and sugar becomes 2 cups. If you are baking, consider weighing the ingredients for accuracy.

Substitution tips

Ingredient substitutions can change moisture and texture. When you swap flours or sweeteners, use trusted conversion ratios and test small batches. A calculator can provide a baseline, but always consider the recipe context.

US vs UK measurement differences

A US tablespoon is slightly different from some international standards. Recipes from different countries may use different cup sizes. If precision matters, rely on weight instead of volume.

Measuring tools that help

A digital kitchen scale is the most reliable tool for baking. Measuring cups are fine for liquids, but dry ingredients can vary depending on how you scoop or pack them.

Pan size adjustments

Changing pan size changes bake times. A larger pan spreads batter thinner and can bake faster. Use a calculator to scale the recipe and monitor baking time closely.

Temperature conversions with gas marks

Some recipes use gas marks or fan oven conversions. Use a conversion chart and adjust by 10-20 degrees if your oven runs hot or cool.

Common mistakes

The most common conversion mistake is assuming 1 cup always equals the same weight. It does not. Use ingredient-specific conversions to avoid dry or dense results.

Scaling for baking vs cooking

Baking is more sensitive to exact ratios, so use weight measurements when possible. Cooking allows more flexibility, but consistent conversions still improve results.

Liquid vs dry measuring

Use liquid measuring cups for liquids and dry cups for dry ingredients. Level off dry ingredients with a straight edge to avoid packing extra volume.

Salt and spice adjustments

When scaling recipes, spices do not always scale linearly. Start with a smaller increase and adjust to taste. This prevents overly strong flavors.
