Converting between grams and cups is a common kitchen conversion that many home cooks need to make. When following recipes, you may see ingredients listed in grams, but your measuring cups measure in cups, ounces, and tablespoons. Converting between the two units allows you to accurately measure ingredients for recipes.
The Quick Answer
450 grams is equivalent to 3.75 cups.
The Long Answer
To convert between grams and cups, you need to know the conversions between grams, ounces, and cups:
- 1 ounce = 28.35 grams
- 1 cup = 8 ounces
- 1 cup = 236.59 ml
So to convert 450 grams to cups, we first convert the grams to ounces, then convert the ounces to cups:
450 grams x (1 ounce/28.35 grams) = 15.87 ounces
15.87 ounces x (1 cup/8 ounces) = 1.98375 cups
Rounding 1.98375 cups to the nearest quarter cup gives us 3.75 cups.
Therefore, 450 grams is equivalent to approximately 3.75 cups.

Converting Cups to Grams
To convert cups to grams, we reverse the process:
Cups x 8 ounces/cup x 28.35 grams/ounce = grams
So for example, to convert 3.75 cups to grams:
3.75 cups x 8 oz/cup x 28.35 g/oz = 840.63 grams
Rounding to the nearest whole number gives us 841 grams.
3.75 cups is approximately 841 grams.

- Helps dietary needs – Helps manage calories, carbs, or other dietary requirements when gram amounts are converted to cups.
By learning to correctly convert between grams and cups, you’ll get reliable results with your recipes and cooking.
Common Gram and Cup Conversions
Here are some of the most common gram to cup conversions:
- 100 grams = 0.44 cup
- 200 grams = 0.87 cup
- 225 grams = 1 cup
- 250 grams = 1.1 cups
- 500 grams = 2.2 cups
- 1 cup = 236 grams
- 2 cups = 473 grams
- 3 cups = 709 grams
Knowing these conversions by heart will help when converting many common recipe ingredient amounts.
Tips for Accurately Measuring Grams and Cups
To get the most accurate measurements when converting between cups and grams:
- Use a kitchen scale – Scales designed for cooking will give you the most precise gram measurements.
- Level off ingredients – Use a straight edge to level off dry ingredients after spooning them into a measuring cup.
- Avoid packing cups – Packing ingredients into a cup can result in too much.
- Use proper cup sizes – Pay attention to cup abbreviations like C, T, t to ensure you use the right cup size.
- Watch the scale – Weigh ingredients directly into the bowl you’ll be using to avoid transfer loss.
Taking steps to measure both grams and cups precisely will lead to better accuracy when converting between the two units.
Common Ingredients and Their Gram to Cup Conversions
Here are the gram to cup conversions for some common baking ingredients:
- All-purpose flour – 125 grams = 1 cup
- Granulated sugar – 200 grams = 1 cup
- Brown sugar – 220 grams = 1 cup
- Butter – 227 grams = 1 cup
- Honey – 340 grams = 1 cup
Knowing the conversions for the ingredients you use often, like flour and sugar, will simplify your gram to cup conversions when baking.
Converting Grams to Cups in Other Ingredients
While dry ingredients like flour and sugar have a straight gram to cup conversion, other ingredients require a few more steps.
Liquids
Since 1 cup liquid = 236.59 ml, you can use this to convert:
- 236.59 grams = 1 cup liquid
- 118.29 grams = 1/2 cup liquid
- 59.15 grams = 1/4 cup liquid
Meat and seafood
Since meat and seafood vary widely in density, use these rough guidelines:
- 113 grams ground meat = 1/2 cup
- 170 grams fish fillet = 1 cup
- 85 grams shrimp = 1/2 cup
Fruits and vegetables
Fruits and vegetables also vary in density. Estimate conversions based on the item’s texture:
- Berry fruits: 150g per cup
- Leafy greens: 80g per cup
- Chopped vegetables: 190g per cup
Tracking an ingredient’s gram weight over time will help refine your personal conversion for that item.
Why Weight is More Precise than Volume
Weights in grams provide more accuracy than volume measures in cups for several reasons:
- Volume measures can vary based on packing or surface tension of liquids.
- Measuring cups can have errors and inconsistencies.
- Items can settle and compact over time, taking up less volume.
- Weight removes human error and ambiguity from the measuring process.
For the most precise results in cooking and baking, weighing ingredients in grams is the best practice.
Should I Use a Scale or Measuring Cups?
Both kitchen scales and measuring cups have their uses when cooking and baking:
- Scales – Great for getting precise weights for baking recipes or portioning servings. Should be used when exact gram amounts are needed.
- Measuring cups – Useful for quick volume measurements. Best for cooking, where precise gram amounts aren’t as critical.
For the most versatility in the kitchen, keep both tools on hand. Use scales for baking and cups for cooking based on convenience and the precision needed.
Tips for Converting Grams to Cups
Here are some top tips for converting between grams and cups:
- Familiarize yourself with common conversions like 1 cup = 236g
- Use a gram to cup conversion chart as a handy reference
- Level off dry ingredients before measuring volume
- Weigh liquids for best results
- Estimate fruits and veggies based on texture
- Confirm conversions for personal ingredients
- Double check recipes using both methods
Learning the basic conversions and using the right techniques will have you easily converting between grams and cups like a pro.
How has the conversion from grams to cups changed over time?
The conversion ratio between grams and cups has not changed over time. The reason is that the gram and the cup are standardized units of measurement.
A gram has been defined the same way since 1795 as one thousandth of a kilogram. The kilogram was redefined in terms of Planck’s constant in 2019, but this did not affect the size of a gram at all.
The cup as a unit of volume was standardized by the United States in the 19th century to be equal to 8 fluid ounces, which is 236.5882365 ml. This definition has remained unchanged since then.
Since the gram and the cup both have fixed definitions, the conversion ratio between them remains constant. No matter when you do the conversion, 450 grams will always equate to roughly 3.75 cups.
However, while the conversion ratio itself does not change, the way it is used and applied has evolved:
- Early adopters – Professional bakers were some of the first to use gram scales in commercial kitchens to improve precision.
- Specialization – As baking became more specialized, more home bakers started using scales and gram weights.
- Digitization – Digital kitchen scales provided ease of use and precision for the average home cook.
- Mass market – Improved technology allowed gram scales to become a common household tool.
So while the 450 grams to 3.75 cups conversion remains constant, digital scales and the trend toward weight-based baking has made the conversion more useful and relevant over time.
The Bottom Line
Converting between grams and cups is a simple process using the right formulas and tools. With some practice, gram to cup conversion can become second nature. Having confidence converting between the two units will serve you well in all sorts of recipes and cooking tasks.
The key takeaways are:
- To convert grams to cups, first convert grams to ounces, then ounces to cups
- To go from cups to grams, multiply cups by ounces per cup and then grams per ounce
- Use digital kitchen scales for the most accurate gram measurements
- Consult conversion charts or tables for common equivalents
- Practice measurement techniques for optimal precision
Knowing how to accurately convert 450 grams to 3.75 cups, as well as other common measurements, will ensure your recipes turn out as planned. So grab those measuring cups and scales and start honing your conversion abilities today.
