⚗️ Fluid Ounces → Pounds

Estimate the weight of a fluid volume by applying material density.

Ideal for recipe scaling, brewing, and chemical dosing when weight is needed for shipping or safety.

Pure water at ~4°C.

Pounds: 1.043176 lb

Kilograms: 0.473176 kg

How to Use This Calculator

1

Enter the fluid volume

Provide the volume in U.S. fluid ounces.

2

Select density

Choose a preset material or enter a custom density in grams per cubic centimeter.

3

Review weight

The calculator reports pounds and kilograms for logistics, labeling, or dosing.

Formula

Cubic centimeters = Fluid ounces × 29.5735296

Mass (grams) = Volume (cc) × Density (g/cc)

Pounds = Grams ÷ 453.59237

Kilograms = Grams ÷ 1,000

Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.

Full Description

Many recipes, lab protocols, and industrial processes specify fluid volume while shipping and inventory systems expect weight. This tool bridges the gap by applying material density.

Densities vary with temperature and composition. Use a preset for common substances or input your own measurement for best accuracy.

The calculator outputs both pounds and kilograms to serve U.S. customary and SI reporting requirements.

Frequently Asked Questions

Where can I find density values?

Consult material safety data sheets, supplier documentation, or density tables. Enter the value in grams per cubic centimeter.

Does the tool support imperial fluid ounces?

The calculation uses U.S. fluid ounces. For Imperial (UK) units, convert the volume to U.S. fluid ounces or add another preset.

What if the density changes with temperature?

Use the density measured at your operating temperature. Density shifts will change the weight result.

Can I get the result in grams?

Multiply kilograms by 1,000 or extend the UI to display grams. The underlying calculation already uses grams internally.
