Ever get frustrated trying to figure out ounces, pint, milliliters, and grams while cooking? Do these random measurements make grocery shopping feel like a math test? Why are there so many confusing units anyway? Don’t stress—this guide will finally make sense of it all!

Quick Conversion Summary

●1 US pint = 16 US fluid ounces (fl oz)
●1 UK pint = 20 UK fluid ounces (fl oz)
●1 US dry pint ≈ 550 ml (varies by ingredient density)
●1 US gallon = 128 US fl oz = 3.785 L, while 1 UK gallon = 160 UK fl oz = 4.546 L

Pint to Ounces Converter

Select Unit System: Pints: Ounces:

US and UK fluid ounces differ slightly (US: 29.57 ml, UK: 28.41 ml).

UK pints are larger (568 ml) than US pints (473 ml).

Avoirdupois ounces (28.35 g) are used for everyday weight, while troy ounces (31.10 g) are used for precious metals.

Key Differences

●A US liquid pint = 16 fluid ounces (473 ml), while a UK (Imperial) pint = 20 fluid ounces (568 ml).

●US dry pints are used for measuring dry goods, and their volume is larger than a liquid pint (550 ml vs. 473 ml), but they are not typically converted into fluid ounces.

●When ordering beer, milk, or liquids, confirm whether the pint is US or UK, as UK pints hold 25% more liquid than US pints.

Ounces, Milliliters, Grams, and Pints Conversion Chart

This table provides quick conversions between ounces (fl oz & oz), milliliters (ml), grams (g), and pints (pt) in both US and UK measurement systems.

Measurement	US Customary System	UK (Imperial) System	Metric Equivalent
1 Ounce (fl oz)	29.57 ml	28.41 ml	~30 ml
1 Pint (pt)	16 US fl oz	20 UK fl oz	473 ml (US) / 568 ml (UK)
1 Quart (qt) (2 Pints)	32 US fl oz	40 UK fl oz	946 ml (US) / 1.13 L (UK)
1 Gallon (gal) (4 Quarts)	128 US fl oz	160 UK fl oz	3.785 L (US) / 4.546 L (UK)
1 Pound (lb) (Weight)	16 oz (Avoirdupois)	16 oz (Avoirdupois)	~454 g
1 Ounce (Weight)	28.35 g (Avoirdupois oz)	28.35 g (Avoirdupois oz)	28.35 g
1 Troy Ounce (Precious Metals)	31.10 g	31.10 g	31.10 g

What Is an Ounce (oz)?

An ounce (oz) is a unit of measurement used for both weight and volume, primarily in the United States and the United Kingdom. The term originates from the Latin word "uncia", meaning "one-twelfth," which was historically used in the Roman measurement system.

Types of Ounces and Their Differences

Type of Ounce	Definition	Equivalent in Metric	Used For
Avoirdupois Ounce (Weight)	1/16 of a pound (lb)	28.35 grams (g)	Weighing solids (e.g., food, metals)
Troy Ounce (Weight)	1/12 of a troy pound	31.10 grams (g)	Precious metals (gold, silver, platinum)
Fluid Ounce (Volume, US)	1/128 of a US gallon	29.57 milliliters (ml)	Measuring liquids (milk, juice, water)
Fluid Ounce (Volume, UK)	1/160 of an Imperial gallon	28.41 milliliters (ml)	Measuring liquids in the UK

Common Ounce Conversions

●1 oz (avoirdupois) = 28.35 g
●1 oz (troy) = 31.10 g
●1 US fluid oz = 29.57 ml
●1 UK fluid oz = 28.41 ml

Key Differences

1.Weight vs. Volume – A fluid ounce (fl oz) measures volume (liquid), while an avoirdupois or troy ounce measures weight (solid materials).

2.US vs. UK Fluid Ounce – A US fluid ounce (29.57ml) is slightly larger than a UK fluid ounce (28.41ml) due to differences in gallon definitions.

3.Troy vs. Avoirdupois Ounce – The troy ounce (31.10g) is heavier than the avoirdupois ounce (28.35g) and is only used for measuring precious metals.

What Is a Pint?

A pint is a unit of volume measurement used primarily in the United States and the United Kingdom. It is commonly used for measuring beer, milk, and other liquids, though historically, dry goods were also measured in pints.

Different Pint Measurements

Type of Pint	Definition	Equivalent in Fluid Ounces	Metric Equivalent	Used In
US Liquid Pint	1/8 of a US gallon	16 US fl oz	473.18 milliliters (ml)	Beverages (beer, milk, juice), cooking
US Dry Pint	1/8 of a US dry gallon	Not commonly used in fl oz	550.61 ml	Dry goods (berries, grains, flour)
UK (Imperial) Pint	1/8 of an Imperial gallon	20 UK fl oz	568.26 ml	Beverages (beer, cider, milk)

Pint Conversions

●1 US pint = 16 US fluid ounces = ~473 ml
●1 UK pint = 20 UK fluid ounces = ~568 ml
●1 US dry pint = ~550 ml
●1 pint = 2 cups
●1 pint = 1/2 quart

Key Differences Between US and UK Pints

1.Size Difference – A UK pint (568ml) is larger than a US pint (473ml) because the Imperial gallon is bigger than the US gallon.

2.Dry vs. Liquid Pint – The US dry pint (550ml) is mainly used for measuring dry ingredients like berries or flour, while the US liquid pint (473ml) is for beverages.

3.Drinking Culture – The UK pub pint is standardized at 20 UK fluid ounces (568ml), while in the US, a pint of beer is 16 US fluid ounces (473ml) unless stated otherwise (e.g., "Imperial Pint" in some bars).
