About Imperial fluid ounce (imp fl oz)
The imperial fluid ounce (imp fl oz) is a unit of volume equal to one twentieth of an imperial pint, approximately 28.413 milliliters. It is used in the United Kingdom and Commonwealth countries, though metric units have replaced it in most commercial contexts. The imperial fluid ounce is slightly smaller than the US fluid ounce (29.574 mL). UK spirits measures are now defined by law in 25 mL and 35 mL metric measures, which do not align exactly with the imperial fluid ounce.
A single spirits measure in a UK bar is 25 mL or 35 mL — close to, but not exactly, one imperial fluid ounce (28.41 mL).
About Cubic meter (m³)
The cubic meter (m³) is the SI derived unit of volume, defined as the volume of a cube with sides of exactly one meter. It is the standard unit for large-volume measurement in science, engineering, construction, and trade. One cubic meter equals 1,000 liters. Natural gas is sold by the cubic meter, concrete is ordered in m³, swimming pools and shipping containers are described in cubic meters, and HVAC airflow is measured in m³/hour.
A standard bathtub holds about 0.15–0.2 m³. A 20-foot shipping container has an internal volume of roughly 33 m³.
Imperial fluid ounce – Frequently Asked Questions
Why did the UK abandon the fluid ounce for spirits but keep the pint for beer?
When the UK metricated in the 1990s, spirits measures were switched to 25 mL and 35 mL because publicans needed precise, legally enforceable pour sizes — and optic dispensers were easy to replace with metric ones. Beer, however, had enormous cultural resistance: the "pint" is deeply embedded in British pub identity, and the Campaign for Real Ale lobbied hard. Parliament granted an explicit exemption allowing draft beer and cider to be sold by the imperial pint. Milk got a similar exemption. The result is a hybrid system where your gin is metric but your beer is imperial.
How many imperial fluid ounces are in a UK pint?
There are exactly 20 imperial fluid ounces in one UK pint (568 mL). In the US system, 1 pint = 16 US fluid ounces (473 mL).
Is the imperial fluid ounce still used?
The imperial fluid ounce is rarely used for commercial transactions in the UK today, which metricated in the 1990s. UK spirits servings are now legally defined in metric (25 mL or 35 mL).
Why is a UK shot 25 mL not one fluid ounce?
When the UK metricated bar measures, the 25 mL "metric measure" replaced older imperial measures. One imperial fl oz (28.41 mL) was not adopted because the EU standardized on 25 mL. So UK shots are not exactly one fl oz.
How many milliliters are in an imperial fluid ounce?
One imperial fluid ounce equals approximately 28.413 mL. One US fluid ounce equals approximately 29.574 mL. Both round to roughly "30 mL" in casual usage, but the precise difference matters in pharmacology.
Cubic meter – Frequently Asked Questions
How many liters are in a cubic meter?
There are exactly 1,000 liters in one cubic meter. This follows from 1 m³ = 1,000 dm³ and 1 dm³ = 1 liter.
Why is natural gas measured in cubic meters?
Natural gas is billed by volume at standard conditions. The cubic meter is the standard billing unit in most metric countries. In the US, natural gas is sold in cubic feet instead.
How big is one cubic meter?
Imagine a cube one meter on each side — about the size of a large washing machine. It holds 1,000 liters of water, which weighs exactly 1,000 kg (one metric tonne) at standard conditions.
What is a cubic meter used for in construction?
Concrete is ordered and priced by the cubic meter. A typical residential house slab might use 10–20 m³ of concrete. Excavated soil, fill material, and gravel are also sold per cubic meter.
How does m³/h relate to airflow?
Cubic meters per hour (m³/h) measures volumetric airflow rate — common in HVAC, ventilation, and industrial fan specifications. A domestic kitchen extractor fan typically moves 200–600 m³/h. The imperial equivalent is cubic feet per minute (CFM).
