Volume vs. Capacity: What's the Difference?
While we often use these terms interchangeably, there's actually a subtle difference between volume and capacity.
Volume
The amount of space an object occupies, regardless of what it's filled with. Think of it as the object's "size" in three dimensions.
Capacity
The amount of substance (usually liquid) that a container can hold. It's about how much can be poured in, not the container's physical size.
For most practical purposes, especially with liquids, these measurements are essentially the same. But technically, a container's capacity might be slightly less than its volume due to the container's walls taking up space.
Cooking Measurements Around the World
Cooking is where volume measurements really matter. But what counts as a "cup" or "teaspoon" varies wildly around the world.
| Country | Cup Size | Tablespoon | Teaspoon |
|---|---|---|---|
| United States | 236 mL | 15 mL | 5 mL |
| United Kingdom | 284 mL | 15 mL | 5 mL |
| Australia | 250 mL | 20 mL | 5 mL |
| Japan | 200 mL | 15 mL | 5 mL |
This inconsistency is why professional recipes often specify weights (grams) instead of volumes. But for home cooking, these variations usually don't make a big difference.
Beyond the Kitchen: Fuel and Shipping
Fuel Economy
Gas mileage is all about volume ratios. How many gallons of fuel does it take to travel a certain distance?
- • US: MPG (miles per gallon)
- • Europe: L/100km (liters per 100 km)
- • Both measure fuel efficiency
Shipping Containers
Cargo capacity is measured in volume. How much space can you fill?
- • Standard shipping pallet: ~1.4 m³
- • 20-foot container: ~33 m³
- • Oil tanker: millions of liters
Common Questions
What's the difference between US and Imperial gallons?
The US gallon (3.785 liters) is smaller than the Imperial gallon (4.546 liters) used in the UK and Canada. The US version is used for fuel economy ratings and is slightly smaller than its Imperial cousin.
Why do recipes use cups and spoons instead of milliliters?
Measuring cups and spoons are convenient household tools that don't require scales. While not as precise as weight measurements, they're perfectly adequate for most home cooking. Professional bakers prefer grams for accuracy.
How do I convert between volume and weight?
You can't directly convert volume to weight without knowing the substance's density. Water weighs about 1 gram per milliliter, but other liquids vary. For example, oil is less dense than water, so the same volume weighs less.
