Quick Answer
In the United States, 1 liquid pint equals 16 US fluid ounces, or about 473 mL.
In the United Kingdom, 1 pint equals 20 Imperial fluid ounces, or about 568 mL.
| Pint Type | Ounces in 1 Pint | Metric Equivalent | Common Use |
|---|---|---|---|
| US liquid pint | 16 US fl oz | 473.176 mL | Cooking, beverages, US water bottles |
| UK / Imperial pint | 20 Imperial fl oz | 568.261 mL | UK beer, cider, milk |
| US dry pint | About 550.61 mL by volume | Not a weight conversion | Berries, dry goods |
Fluid ounces measure volume. Ounces measure weight. A pint is a volume measurement, not a weight measurement.
For drinkware brands, this matters because most water bottle capacities are labeled in fluid ounces, such as 16 oz, 20 oz, 24 oz, 32 oz, and 40 oz.
How Many Ounces Are in a US Pint?
A US liquid pint contains:
1 US pint = 16 US fluid ounces
It also equals:
- 2 US cups
- 1/2 US quart
- 1/8 US gallon
- About 473 mL
For example, a 16 oz water bottle is approximately one US liquid pint.
For brands choosing bottle sizes, this conversion helps customers understand capacity more easily. You can also read our water bottle size guide for brands.
How Many Ounces Are in a UK Pint?
A UK or Imperial pint contains:
1 Imperial pint = 20 Imperial fluid ounces
It equals about 568.261 mL.
This is why a pint of beer in the UK is larger than a pint in the US. A UK pint is about 20% larger by volume than a US pint.
For international drinkware brands, this matters when selling to different markets. A bottle promoted as “1 pint” in the US may not match what UK customers expect from a pint.

Pint to Ounces Conversion Formula
For US liquid measurements:
Pints × 16 = US fluid ounces
| US Pints | US Fluid Ounces |
| 1/4 pint | 4 fl oz |
| 1/2 pint | 8 fl oz |
| 1 pint | 16 fl oz |
| 1.5 pints | 24 fl oz |
| 2 pints | 32 fl oz |
| 4 pints | 64 fl oz |
For Imperial measurements:
Pints × 20 = Imperial fluid ounces
| Imperial Pints | Imperial Fluid Ounces |
| 1/2 pint | 10 fl oz |
| 1 pint | 20 fl oz |
| 2 pints | 40 fl oz |
| 4 pints | 80 fl oz |
Fluid Ounces vs Ounces
A fluid ounce, written as fl oz, measures volume.
Use fluid ounces for water, milk, juice, coffee, beer, soup, and bottle capacity.
An ounce, written as oz, usually measures weight.
Use weight ounces for flour, sugar, nuts, chocolate, berries, meat, and other dry ingredients.
This is why 16 fluid ounces of water is not the same concept as 16 ounces of flour by weight.
What Pint Sizes Mean for Water Bottle Brands
For drinkware brands, pints are more than a kitchen conversion. They help customers understand bottle capacity quickly.
| Capacity | Pint Equivalent | Brand Positioning | Buyer Consideration |
| 12 oz | 0.75 pint | Kids, coffee, compact daily use | Lightweight, smaller packaging |
| 16 oz | 1 pint | School, office, commuter bottle | Familiar size, easy daily use |
| 20 oz | 1.25 pints | Retail bottle, corporate gift | Balanced capacity and portability |
| 24 oz | 1.5 pints | Gym, sports, outdoor use | Larger hydration without too much bulk |
| 32 oz | 2 pints | Fitness, hiking, workday hydration | Higher perceived value, larger carton |
| 40 oz | 2.5 pints | Tumbler, travel, long-day hydration | Popular lifestyle size |
| 64 oz | 4 pints | Camping, outdoor, high-volume hydration | Heavier when full, higher shipping impact |
Topnovo Buyer Tip
For US drinkware markets, 16 oz, 20 oz, 24 oz, 32 oz, and 40 oz are usually easier for customers to understand than pint-based labels.
Before sampling, brands should compare:
- Filled weight
- Hand feel
- Cup holder compatibility
- Lid type
- Packaging size
- Carton quantity
- Shipping cost
- Target retail price
