Kitchen Measurement Conversions
Free kitchen conversion calculators for every cooking and baking measurement. Convert cups to grams, tablespoons to ml, ounces to grams, and oven temperatures — all instant, all free, no login required.
Kitchen measurement conversions are one of the most common problems home cooks and bakers face. Recipes from different countries use different measurement systems — US recipes call for cups, UK recipes use grams, and Australian recipes sometimes use a tablespoon that's a third larger than the UK version. Getting the conversion right is the difference between a perfect bake and a disappointing one.
The most important thing to understand about kitchen conversions is that cups are a volume measurement, not a weight measurement. One cup of flour weighs 125 grams, but one cup of caster sugar weighs 200 grams, and one cup of butter weighs 227 grams. You cannot apply a single conversion factor across all ingredients — each ingredient has its own density. Our cups-to-grams calculator handles this automatically for 25+ baking ingredients.
For tablespoon and teaspoon conversions, the key variable is which country the recipe comes from. UK and US tablespoons are both 15ml (close enough for practical purposes). Australian tablespoons are 20ml — one third more. Three Australian tablespoons (60ml) is equivalent to four UK tablespoons. Always check the recipe origin before measuring.
Oven temperature conversions matter in every international recipe. British and European recipes use Celsius; American recipes use Fahrenheit. Older British recipes use gas mark. Our oven temperature converter handles all three, and also calculates the fan oven equivalent (typically 20°C lower than the conventional setting).
Volume Conversions
Convert between cups, tablespoons, teaspoons, millilitres and litres.
Cups to Grams Converter
Convert cups to grams for flour, sugar, butter and 25+ baking ingredients. Ingredient-aware — not a generic estimate.
e.g. 1 cup flour = 125g · 1 cup caster sugar = 200g
Grams to Cups Converter
Convert gram weights back to cups. Useful when you have weighed ingredients but need to understand the cup equivalent.
e.g. 250g flour = 2 cups · 200g sugar = 1 cup
Tablespoons to ML Converter
Convert tablespoons to millilitres for cooking and baking. Supports UK/US (15ml) and Australian (20ml) tablespoon sizes.
e.g. 1 tbsp = 15ml · 4 tbsp = 60ml
Teaspoons to ML Converter
Convert teaspoons to millilitres. Essential for small liquid measurements — vanilla extract, lemon juice, liquid spices.
e.g. 1 tsp = 5ml · 3 tsp = 15ml (= 1 tbsp)
Tablespoons to Grams
Convert tablespoon measurements to grams by ingredient type. Butter, flour, sugar and more behave differently by volume.
e.g. 1 tbsp butter = 14g · 1 tbsp flour = 8g
Cups to ML Converter
Convert cups to millilitres. Straightforward volume conversion between US cups (236ml) and UK cups (250ml).
e.g. 1 US cup = 237ml · ½ cup = 118ml
ML to Cups Converter
Convert millilitres to cups. Useful when a recipe lists liquids in ml but your measuring equipment shows cups.
e.g. 500ml = 2.1 US cups · 250ml = 1 UK cup
Litres to Cups
Convert litres to cups for large-batch cooking and drinks. Covers US, UK and Australian cup sizes.
e.g. 1 litre = 4.23 US cups · 1 litre = 4 metric cups

| 1 cup (UK/AU/Metric) | 250ml | 16⅔ | 50 |
| 1 pint (UK) | 568ml | 37⅞ | 113½ |
Weight Conversions
Convert between grams, ounces, and volume measurements by ingredient.
Ounces to Grams Converter
Convert ounces to grams for cooking and baking. US recipes frequently list weights in oz; convert to grams for a kitchen scale.
e.g. 4 oz = 113g · 8 oz = 227g · 16 oz = 454g
Grams to Ounces Converter
Convert gram weights to ounces. Helpful when following US recipes on a UK kitchen scale.
e.g. 100g = 3.53 oz · 250g = 8.82 oz
Teaspoons to Grams
Convert teaspoon amounts to grams by ingredient. Salt, baking powder, spices and sugar all differ in density.
e.g. 1 tsp salt = 6g · 1 tsp baking powder = 4g
Quick Reference — Weight
Common baking ingredients — 1 cup in grams.
| Ingredient | 1 US Cup | ½ Cup | ¼ Cup |
|---|---|---|---|
| Plain / All-Purpose Flour | 125g | 63g | 31g |
| Self-Raising Flour | 125g | 63g | 31g |
| Wholemeal / Whole Wheat Flour | 120g | 60g | 30g |

All values are for US cups (236.6ml). UK/AU cups (250ml) give approximately 6% more. Use the full calculator for precise amounts →
Oven Temperature Conversions
Convert between Celsius, Fahrenheit, gas mark and fan oven settings.
Celsius to Fahrenheit Oven Converter
Convert oven temperatures from Celsius to Fahrenheit with gas mark and fan oven settings. Covers all common baking temperatures.
e.g. 180°C = 356°F = Gas 4 · 200°C = 392°F = Gas 6
Fahrenheit to Celsius Oven Converter
Convert US recipe oven temperatures from Fahrenheit to Celsius. Includes gas mark and fan oven adjustment.
e.g. 350°F = 177°C · 400°F = 204°C
Gas Mark to Celsius
Convert gas mark settings to Celsius and Fahrenheit. Essential for older UK recipes that use gas mark notation.
e.g. Gas 4 = 180°C · Gas 6 = 200°C · Gas 7 = 220°C
Fan Oven Converter
Convert conventional oven temperatures to fan oven settings. Fan ovens run hotter — the standard adjustment is −20°C.
e.g. 180°C conventional = 160°C fan

Tips for Accurate Kitchen Measurements
Weigh, don't cup — kitchen scales give the most accurate results. A cup of flour can weigh anywhere from 100g to 160g depending on how it's measured. Grams are always consistent.
Spoon flour into the cup — never scoop directly from the bag. Scooping compacts the flour and can add 20–30% extra weight. Spoon it in lightly, then level off with a straight edge.
Check the recipe's country — UK tablespoons (15ml) and Australian tablespoons (20ml) are not the same. If a recipe from Australia calls for 3 tablespoons, use 4 UK tablespoons.
US cups vs UK cups — a US cup is 237ml, a UK/AU cup is 250ml. The difference is about 5%. Small in casual cooking, but significant in precision baking. Always select the right cup size in our converters.
Fan ovens run hotter — reduce the temperature by 20°C (35°F) compared to a conventional oven setting. If a recipe calls for 180°C, use 160°C in a fan oven.
Get an oven thermometer — most home ovens run 10–25°C off their dial setting. An inexpensive oven thermometer tells you the actual temperature, removing one of the most common causes of baking failure.
