About these units
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.
Femtoliter (fL)
A femtoliter represents 10⁻¹⁵ liters and is commonly used in hematology, particularly in describing red blood cell size. A typical red blood cell has a volume of roughly 80–100 fL, making this unit ideal for medical diagnostics. Beyond medicine, femtoliters are used in microfluidics and nanoparticle research, where reaction chambers or droplets often hold only a few dozen femtoliters of liquid. The femtoliter exemplifies how modern science pushes measurement into realms dominated by statistical motion, molecular interactions, and quantum effects—scales that once seemed impossible to quantify.
