A cubic decimeter (dm3) is a unit used to measure volume in the metric system.
It is defined as the volume of a cube with sides that are one decimeter (10 cm) long.
Crucially, one cubic decimeter is precisely equal to one liter (L).
Yes, they are the same!
The most important thing to remember is that one cubic decimeter is precisely equal to 1 liter (1 dm3 = 1 L). This simple one-to-one relationship makes it a handy unit for measuring liquids.
Imagine a cube that is 10 cm tall, 10 cm wide, and 10 cm long—it holds exactly one liter of water.
This link between volume (from length) and capacity (liters) is a core principle of the metric system.
The cubic decimeter is a perfect "bridge" between smaller and larger volume measurements. Here's how it connects:
From dm3 to Cubic Centimeters (cm3): Since 1 decimeter = 10 centimeters, a cubic decimeter contains 10 x 10 x 10 = 1,000 cubic centimeters (cm3).
From dm3 to Milliliters (mL): Because 1 cm3 is identical to 1 milliliter (mL), it means that 1 dm3 also equals 1,000 mL.
From dm3 to Cubic Meters (m3): To measure larger spaces, you need 1,000 cubic decimeters to make one cubic meter (1 m3).
While you might not hear "cubic decimeter" in everyday conversation, it is essential in many scientific and technical fields:
Chemistry: Solution concentrations are often measured in moles per cubic decimeter (mol/dm3).
Engineering: The size of a car engine (its displacement) is measured in liters, which is a direct measurement of cubic decimeters.
Manufacturing: It's used for precise calculations where accuracy is critical.
A cup is a unit of volume measurement equal to 8 fluid ounces (fl oz).
It's one of the most common measurements used in recipes for cooking and baking, especially in the United States.
While they share the same name, not all cups are created equal.
A US customary cup is defined as 8 US fluid ounces (approximately 237 milliliters).
However, the metric cup used in countries like Australia, Canada, and New Zealand is standardized to 250 milliliters.
This slight difference is crucial to remember when following international recipes to ensure the correct ingredient proportions.

The name of the measurement isn't a coincidence. Before standardized units became common, recipes relied on informal measurements using everyday kitchenware.
The "cup" literally referred to the volume of a standard teacup. Over time, this was standardized into the precise unit we use today.
Although the unit of volume (8 fl oz) remains the same, the tools used to measure dry and liquid ingredients differ for a reason.
Using the wrong type can lead to inaccurate measurements.
