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 Cubic millimeter (mm³)
A cubic millimeter (mm³) is the volume of a cube with sides of one millimeter, equal to one microliter (0.001 mL). It is among the smallest practical volume units in science and engineering, used in microfabrication, inkjet technology, microfluidics, and medical dosing. Raindrops are commonly estimated at 50 mm³, while a standard inkjet printer deposits droplets of 1–30 mm³. The cubic millimeter belongs to the metric system and sits three orders of magnitude below the milliliter.
A single raindrop is roughly 50 mm³. A standard inkjet printer droplet ranges from 1 to 30 mm³.
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.
Cubic millimeter – Frequently Asked Questions
What is a cubic millimeter?
A cubic millimeter (mm³) is the volume of a cube measuring 1 mm on each side. It equals one microliter (μL) or 0.001 milliliters, making it one of the smallest named volume units in everyday scientific use.
How many cubic millimeters are in a milliliter?
There are exactly 1,000 cubic millimeters in one milliliter. This follows from 1 mL = 1 cm³ and 1 cm³ = 1,000 mm³ (since 10³ = 1,000).
What is measured in cubic millimeters?
Cubic millimeters are used in microfluidics, inkjet printing, medical dosing, and precision manufacturing. Inkjet printers deposit droplets of 1–30 mm³; medical microsampling devices handle volumes in the 10–100 mm³ range.
How big is a raindrop in cubic millimeters?
A typical raindrop is roughly 20–100 mm³ (0.02–0.1 mL), with an average often cited around 50 mm³. Very small drizzle drops can be under 10 mm³, while large storm drops approach 100 mm³.
How do cubic millimeters relate to cubic centimeters?
One cubic centimeter (cm³) equals 1,000 cubic millimeters (mm³). Since 1 cm³ = 1 mL, the chain is: 1 cm³ = 1 mL = 1,000 mm³.
