Overview
A volume converter is invaluable for cooks, engineers, scientists, or anyone working with liquids, gases, or solids in volumetric terms. This tool converts between common units—milliliters, liters, cubic centimeters, cubic meters, cubic inches, cubic feet, cups, pints, quarts, gallons (US & UK), and, in Advanced Mode, teaspoons, tablespoons, fluid ounces, barrels, cubic rods, cubic chains, cubic miles, etc. Simply toggle “Advanced Mode” to expand the list of units, select your “From” and “To” units, enter a numeric value, and click “Convert” for accurate results to six decimal places.
All conversion factors reference internationally recognized constants. And because it’s fully responsive, you can use it on desktop, tablet, or mobile without registration.
Formula & Methodology
Conversions proceed by first converting the input to cubic meters (m³), then converting that cubic‐meter value into the target unit. Example: Convert 2 gallons (US) to liters:
- Convert 2 Gal (US) → m³: $$2 \times 0.003785411784 \; (\text{m³ per US gallon}) = 0.007570823568 \;\text{m³}.$$
- Convert 0.007570823568 m³ → L: $$0.007570823568 \times 1000 = 7.570823568 \;\text{L}.$$
Key conversion factors used (to cubic meters): • 1 mm³ = 1e−9 m³ • 1 cm³ = 1e−6 m³ • 1 mL = 1e−6 m³ • 1 L = 1e−3 m³ • 1 m³ = 1 m³ • 1 km³ = 1e9 m³ • 1 in³ = 1.6387064e−5 m³ • 1 ft³ = 0.028316846592 m³ • 1 yd³ = 0.764554857984 m³ • 1 US gallon = 0.003785411784 m³ • 1 US quart = 0.000946352946 m³ • 1 US pint = 0.000473176473 m³ • 1 US cup = 0.0002365882365 m³ • 1 UK gallon = 0.00454609 m³ • 1 US barrel = 0.119240471196 m³ • 1 US fl oz = 2.95735295625e−5 m³ • 1 US tbsp = 1.478676478125e−5 m³ • 1 US tsp = 4.92892159375e−6 m³ • 1 cubic mile = 4.168181825e9 m³ • 1 cubic rod = 0.101164 m³ • 1 cubic chain = 6.746715 m³
Examples
-
Convert 3 liters to US gallons:
$$3 \times 0.001 = 0.003 \;\text{m³},$$
$$0.003 \div 0.003785411784 \approx 0.792516 \;\text{US gal}.$$ -
Convert 5000 mL to cups (US):
$$5000 \times 1e−6 = 0.005 \;\text{m³},$$
$$0.005 \div 0.0002365882365 \approx 21.133435 \;\text{US cups}.$$ -
Convert 2 cubic feet to liters:
$$2 \times 0.028316846592 = 0.056633693184 \;\text{m³},$$
$$0.056633693184 \times 1000 = 56.633693184 \;\text{L}.$$ -
Convert 1 barrel (US) to cubic meters:
$$1 \times 0.119240471196 = 0.119240471196 \;\text{m³}.$$ -
Convert 10 barrels to fluid ounces (US):
$$10 \times 0.119240471196 = 1.19240471196 \;\text{m³},$$
$$1.19240471196 \div 2.95735295625e−5 \approx 40,314.251 \;\text{US fl oz}.$$
Frequently Asked Questions
Which basic units can I convert?
This converter supports: cubic millimeter (mm³), cubic centimeter (cm³), milliliter (mL), liter (L), cubic meter (m³), cubic kilometer (km³), cubic inch (in³), cubic foot (ft³), cubic yard (yd³), US gallon, US quart, US pint, and US cup.
Which advanced units are available?
In Advanced Mode, you’ll see: cubic mile (mi³), cubic rod, cubic chain, US barrel, US fluid ounce, US tablespoon, US teaspoon, and UK gallon.
How precise are these conversions?
All factors use authoritative sources, and results display to six decimal places. You may round or truncate if needed for your specific application.
When is Advanced Mode useful?
Advanced units are helpful in chemistry (barrel), cooking (teaspoon, tablespoon, fl oz), surveying (cubic chain, rod), and astronomical contexts (cubic mile). Leave it unchecked to focus on everyday units.
Can I use this on my phone?
Yes. The design is fully responsive and optimized for mobile, tablet, and desktop. No installation or registration required.
