About these units
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.
CCF (ccf)
The abbreviation CCF stands for centum cubic feet, meaning 100 cubic feet. It is widely used by water and natural gas utilities to measure residential and industrial consumption. Water bills in many US cities list usage in CCF, balancing numerical convenience with practical scale. For example, a household may consume 5–12 CCF per month, depending on climate and household size. Because natural gas companies also use CCF, the unit plays a central role in energy billing, conservation programs, and environmental reporting. It is a key bridge between technical engineering measurements and everyday consumer usage.
