To liters: 1 dm³ = 1 L (exact). To cubic meters: divide by 1,000. To gallons (US): multiply by 0.264172.
1 dm³ = 0.001 m³ = 1 L = 1,000 cm³ = 10⁶ mm³. One cubic meter contains 1,000 dm³.
For example, 1 Cubic Decimeter (dm³) = 1.000000e+18 Attoliter (aL).

The cubic decimeter is a unit of volume equal to a cube with edges of one decimeter (0.001 m³), and is exactly equal to one liter.
1 dm³ = 0.001 m³ = 1 L = 1,000 cm³ = 10⁶ mm³. One cubic meter contains 1,000 dm³.
To liters: 1 dm³ = 1 L (exact). To cubic meters: divide by 1,000. To gallons (US): multiply by 0.264172.
Used interchangeably with liters — applicable to beverage volumes, fuel measurements, and container sizing.
The dm³ is one of the few SI-derived units that has a more popular non-SI alternative (the liter) used even in scientific contexts.
Not recognizing that 1 dm³ = 1 L exactly. Some assume they are only approximately equal due to historical definitions.
Visualize a cube that is 10 cm × 10 cm × 10 cm — that is one dm³ and also exactly one liter.
The attoliter is an extremely small unit of volume equal to 10⁻¹⁸ liters, or one quintillionth of a liter.
1 aL = 10⁻¹⁸ L = 10⁻²¹ m³ = 10⁻¹⁵ µL. One femtoliter = 1,000 aL.
To liters: multiply by 10⁻¹⁸. To femtoliters: divide by 1,000. To cubic nanometers: 1 aL = 10⁶ nm³.
Measuring individual molecular reaction volumes, nano-droplet volumes, and single-cell compartments.
A typical virus capsid can enclose a volume of just a few attoliters. The interior of a ribosome is measured in attoliters.
Confusing attoliters with femtoliters — there are 1,000 aL in 1 fL. The scale difference is enormous.
Prefix ladder: milli → micro → nano → pico → femto → atto. Each step is 10⁻³ smaller than the last.
