About Imperial cup (imp cup)
The imperial cup is a unit of volume equal to half an imperial pint, approximately 284.1 milliliters. It was historically used in British cooking recipes and is still found in older UK and Commonwealth cookbooks. The imperial cup is distinct from the US legal cup (240 mL) and the Australian metric cup (250 mL). Since the UK's adoption of metric measures, the imperial cup has largely fallen out of use, replaced by milliliters and the 250 mL metric cup.
Older British recipes (pre-1970s) may call for cups measured as imperial cups (~284 mL). A standard UK teacup holds about 1 imperial cup.
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 cup – Frequently Asked Questions
How many milliliters is an imperial cup?
One imperial cup equals approximately 284.1 mL — half an imperial pint (568 mL). This is larger than both the US legal cup (240 mL) and the Australian metric cup (250 mL).
Is the imperial cup still used in the UK?
The imperial cup is largely obsolete in modern UK cooking, which now uses metric measurements. It may appear in old British recipe books published before the 1970s metric changeover.
How does the imperial cup compare to the US cup?
An imperial cup (284.1 mL) is about 18% larger than a US legal cup (240 mL). When using old British recipes in the US, 1 imperial cup ≈ 1.18 US cups — worth adjusting in baking.
What replaced the imperial cup in British recipes?
Modern British recipes use metric measures: milliliters (mL) for liquids and grams (g) for solids. The BBC and major UK food publishers phased out cup measures in favor of grams through the 1970s–1990s.
How many imperial cups are in an imperial gallon?
There are 16 imperial cups in one imperial gallon (8 pints × 2 cups/pint = 16 cups).
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).
