About these units
Cubic Millimeter (mm³)
A cubic millimeter is the volume of a cube exactly 1 millimeter on each side, equal to 10⁻⁹ cubic meters or 0.001 milliliters. It is a very small volume, frequently used in medical imaging, microfluidics, materials science, and cell biology. In anatomy and radiology, tissue or tumor volumes are often quantified in cubic millimeters to express small but clinically significant structures. In engineering, mm³ can describe the displacement of precision components or the volume of micro-machined cavities. Microfluidic research—where entire laboratories are miniaturized onto chips—depends heavily on mm³ and smaller units, as channels and chambers hold extremely tiny volumes. Its precision scale makes it invaluable for applications requiring meticulous material control.
Teaspoon (UK) (tsp (UK))
The UK teaspoon is defined as 5 milliliters, a value adopted in modern culinary and medical standards. Historically, however, its size varied considerably, often ranging from 4 to 6 mL depending on household spoons, region, or era. The modern 5 mL standardization brought consistency to recipes, pharmaceutical dosing instructions, and food labeling. Because teaspoons were once everyday household items rather than calibrated instruments, the move toward fixed metric equivalents significantly improved recipe reliability and medical accuracy. Despite the shift to SI units, the teaspoon endures as a culturally intuitive volume measure used in cooking and oral medication dosing, tying contemporary practice to long-standing domestic traditions.
