Converting Cubic Feet to Liters (ft³ to L) is a common task when comparing household appliances and storage equipment. While the US often measures refrigerator capacity and gas tanks in cubic feet, the rest of the world uses Liters. 1 Cubic Foot is equal to approximately 28.32 Liters. This means that a volume measured in cubic feet is numerically much smaller than the same volume in liters.

The Formula
Multiply the Cubic Feet by approximately 28.32:
ft³ × 28.32 = Liters
Example
If a refrigerator has a capacity of 10 cubic feet:
10 × 28.32 = 283.2 Liters

A great way to visualize this is to imagine 14 two-liter soda bottles. All of that liquid would fit perfectly inside a box that is exactly 1 foot long, wide, and deep.
Frequently Asked Questions
One cubic foot is equivalent to 28.3168 liters. This conversion is vital for understanding the capacity of household items sold in the US (like trash cans or refrigerators) when comparing them to international models that list volume in liters.
If you need to do the math quickly without a calculator, multiplying by 30 and then subtracting about 5% will give you a very close answer. For example, if you have 5 cubic feet: $5 \times 30 = 150$. Subtracting a little bit gets you close to the actual answer of 141.5 liters.
In the US, fish tanks are often sold by their dimensions in inches or total cubic feet. However, water treatments, heater ratings, and pump flow rates are almost always calculated in liters. This tool helps you bridge that gap so your fish stay healthy and the water stays clean.
