How to convert liters to ounces
fluid ounces = liters × 33.814
Example: 1.5 L × 33.814 = 50.72 fl oz.
Multiply liters by 33.81 to get US fluid ounces. A liter sits just above a US quart, which is 32 fl oz, so every liter gives you a little more than a quart's worth of ounces.
Half a liter is 16.91 fl oz, and three liters come to 101.4 fl oz. For amounts under a quarter liter, the liters to milliliters page is often the easier route.
These are fluid ounces, a measure of space. A liter of honey and a liter of water fill the same bottle, but they do not weigh the same number of ounces.
US vs UK fluid ounces
The British fluid ounce is the smaller of the two, 28.41 ml against 29.57 ml in the US. A liter therefore holds more of them: 35.2 imp fl oz.
You will rarely need that figure for shopping in Great Britain. Goods there must be sold in metric units, and an imperial amount may only appear next to the metric one without standing out more (GOV.UK). It matters for older British recipes, where fluid ounces mean the imperial size.
| Unit | Size | Used in |
|---|---|---|
| US fluid ounce | 29.57 ml | US |
| imperial fluid ounce | 28.41 ml | UK |
How many cans or bottles fit in a liter?
If you keep track of drinks by the can or bottle, it helps to know how many of each add up to a liter:
- 12 fl oz cans: 2.8 per liter
- 16.9 fl oz bottles: 2 per liter
- 20 fl oz bottles: 1.7 per liter
Three cans of 12 fl oz therefore hold a little more than a liter, while two 20 fl oz bottles hold well over one.
Liters and ounces: questions
Is 32 oz the same as 1 liter (litre)?
No, a liter is a bit bigger. 32 fl oz make one US quart, which is 0.9464 L. A bottle marked 32 fl oz holds slightly less than one marked 1 L, so the two are close but not interchangeable in a recipe that needs precision.
Is 1 liter 64 oz?
No. 64 fl oz is nearly two liters, 1.893 L, and it equals half a US gallon. One liter is only a little more than half of that, so a 64 fl oz jug holds almost two liter bottles' worth.
Is 16 oz the same as 1 liter?
No. 16 fl oz is one US pint, 0.4732 L, which is under half a liter. It takes a little more than two US pints of water to fill a liter bottle.
How many 8 oz glasses of water are in 1 liter?
A liter fills 4.2 glasses of 8 fl oz. That is four full glasses plus a small splash. The count is the same for US cups, since a cup also holds 8 fl oz.
How many ounces are in 0.75 liters?
0.75 L, the same as 750 ml, holds 25.36 fl oz. The same bottle holds 26.4 imperial fluid ounces, or 3.17 cups in US measure. Poured into a 32 fl oz jug, it fills a little more than three quarters of it.
