About these units
Cubic Decimeter (dm³)
A cubic decimeter is defined as 1 liter, since it is the volume of a cube 10 centimeters per side. Though equivalent to the liter, dm³ is often used in engineering and physics because it fits neatly into the SI geometric framework. This unit is convenient when working with densities (kg/dm³), where the equivalence of 1 dm³ and 1 L simplifies many calculations involving fluids and materials. While the liter dominates everyday usage, the cubic decimeter is favored in technical contexts where a strong geometric interpretation is needed—for example, in tank sizing, volumetric flow calculations, or experiments involving water displacement.
Quart (US) (qt (US))
A US quart equals 32 US fluid ounces or 946 milliliters, exactly 1/4 of a US gallon. It is commonly used for milk, juice, motor oil, and household chemicals. The quart's convenient scale makes it ideal for medium-sized liquid quantities—larger than a pint but smaller than a gallon. It remains widely used in American kitchens, automotive maintenance, and everyday shopping. Like other US customary units, the quart persists because consumers and industries have longstanding infrastructures built around it.
