About Cubic foot (ft³)
A cubic foot (ft³) is the volume of a cube with 1-foot sides, equal to approximately 28.317 liters or 7.48 US gallons. It is used in the United States for natural gas billing, refrigerator capacity, aquarium size, concrete orders, and shipping container dimensions. Refrigerators are rated in cubic feet of storage, natural gas consumption is billed in cubic feet, and HVAC airflow is measured in cubic feet per minute (CFM).
A full-size refrigerator is typically 18–28 ft³. Natural gas is billed in CCF (hundreds of cubic feet) in the US.
About US teaspoon (tsp)
The US teaspoon (tsp) is a unit of culinary volume equal to approximately 4.929 milliliters, one third of a US tablespoon. It is one of the smallest standard US customary volume units, used in cooking, baking, and medicine for small ingredient quantities. The US teaspoon differs from the metric teaspoon (exactly 5 mL) and the imperial teaspoon (about 5.92 mL). In medicine, 5 mL is the standardized dosing teaspoon.
A standard dose of liquid children's medicine is one 5 mL teaspoon. A recipe calling for 1 tsp of vanilla extract uses about 4.93 mL.
Cubic foot – Frequently Asked Questions
How many liters are in a cubic foot?
One cubic foot equals approximately 28.317 liters. Since 1 foot = 30.48 cm, 1 ft³ = 30.48³ cm³ = 28,316.8 cm³ = 28.317 liters.
Why is natural gas measured in cubic feet in the US?
The US gas industry adopted cubic feet before metrication became widespread. Natural gas is billed in CCF (hundred cubic feet) or therms (≈ 100 ft³ by energy content). Metric countries use cubic meters.
What does cubic feet mean for refrigerators?
Refrigerator capacity is rated in cubic feet of internal storage. A compact dorm fridge is 1–4 ft³; a standard family fridge is 18–22 ft³; a large French door model can exceed 28 ft³.
What is CFM (cubic feet per minute)?
CFM measures volumetric airflow rate. HVAC systems, range hoods, and fans are rated in CFM. A typical home range hood requires 100–600 CFM; a whole-home HVAC system might move 2,000 CFM.
How many US gallons are in a cubic foot?
One cubic foot equals approximately 7.48 US liquid gallons. This is commonly used in plumbing, aquarium sizing, and pool volume calculations.
US teaspoon – Frequently Asked Questions
How many milliliters is a US teaspoon?
One US teaspoon equals approximately 4.929 mL, typically rounded to 5 mL in medicine and 4.93 mL in precise culinary conversions. The metric teaspoon used in Australia and Canada is exactly 5 mL.
What is the difference between a US teaspoon and an imperial teaspoon?
A US teaspoon is about 4.93 mL; an imperial (UK) teaspoon is about 5.92 mL — approximately 20% larger. This difference can affect recipes crossing US and UK sources, particularly for spices and leavening agents.
How many teaspoons are in a tablespoon?
In the US system, 3 teaspoons equal 1 tablespoon (3 × 4.929 mL = 14.787 mL). The metric equivalent is the same ratio: 3 × 5 mL = 15 mL tablespoon.
Is a medicine teaspoon the same as a cooking teaspoon?
Not exactly. Medicine dosing uses a standardized 5 mL teaspoon, while the US cooking teaspoon is about 4.93 mL. For medication accuracy, always use a calibrated oral syringe rather than a kitchen teaspoon, which can vary from 3 to 7 mL.
How many US teaspoons are in a cup?
There are 48 US teaspoons in one US cup: 1 cup = 16 tablespoons = 48 teaspoons.
