What is the equivalent of 1 fluid ounce in liters?

1. 0.12 l

2. 0.24 l

3. 0.47 l

4. 0.5 l

The correct answer is: 0.24 l

To determine the equivalent of 1 fluid ounce in liters, it is important to use the conversion factor between these two units of measurement. One fluid ounce is equivalent to approximately 0.0295735 liters. When converting 1 fluid ounce to liters, you perform the calculation: 1 fluid ounce × 0.0295735 liters/fluid ounce ≈ 0.02957 liters. However, since the question likely expects a more commonly acceptable rounded figure, it can be further approximated to about 0.03 liters. If you are looking for a more approximate value that is rounded and can be easily compared, you find that approximately 33.814 fluid ounces equal 1 liter, meaning 1 fluid ounce is about 1/33.814 liters, which reinforces the initial conversion result. The correct answer is therefore closest to 0.03 liters (or specifically 0.02957), which does not match the selected option of 0.24 liters, affirming that it is not the equivalent of 1 fluid ounce in liters. The standard and widely accepted value for this conversion is about 0.030 liters. So, reviewing common choices, one would find alternatives that accurately reflect the 1 fluid ounce to liter
