Milliliter (mL)
Definition: One thousandth of a liter (10⁻³ L), equal to exactly one cubic centimeter.
History: Introduced alongside the liter in the French metric reform of the 1790s as a decimal subdivision suited to small quantities, and later formalized worldwide through the 1875 Metre Convention.
Current use: The standard unit for medicine dosing, cooking recipes outside the US, cosmetics and beverage packaging, and laboratory measurement in virtually every country that uses the metric system.
Cubic Inch (in³)
Definition: The volume of a cube one inch on each side, equal to exactly 0.016387064 liters.
History: Derived the same way as the cubic foot, as a geometric cube of the inch; it became especially associated with mechanical engineering once precision manufacturing required small-volume measurements.
Current use: Historically the standard unit for automobile engine displacement in the US (e.g. a "350 cubic-inch" V8) before most manufacturers switched to liters, and still used for small mechanical component volumes.

About These Parameters
- Value
- The number you want to convert, expressed in the "From" unit. Accepts decimals.
- From Unit
- The unit your input value is currently measured in.
- To Unit
- The unit you want the result converted into. Use the swap button to flip From and To instantly.
How Volume Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to the liter. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Milliliter → Cubic Inch: multiply by 0.061023744. For example, 1 mL × 0.061023744 = 0.061023744 in³.
US Gallons vs. UK Imperial Gallons
This converter uses US customary volume units exclusively (fluid ounce, cup, pint, quart, gallon), which are not the same size as their UK imperial counterparts. A US gallon is exactly 3.785411784 liters, while a UK imperial gallon is about 4.546 liters — roughly 20% larger. Both systems trace back to old English measures, but the US kept the older wine-gallon standard after 1776 while Britain redefined its units in 1824. This mismatch is a common source of confusion when comparing fuel economy or recipe measurements between the US and UK.
Metric vs. US Customary Volume
The metric units on this page (milliliter, liter, cubic meter) all scale by powers of ten, so converting between them is just moving a decimal point. US customary units (fluid ounce, cup, pint, quart, gallon) use irregular multiples — 8 fluid ounces to a cup, 2 cups to a pint, 2 pints to a quart, 4 quarts to a gallon — inherited from centuries-old English liquid-measure tradition rather than a decimal system.
Volume in the Kitchen
Cups, pints, and quarts are primarily cooking and baking units in the United States — most other countries measure recipe ingredients by weight (grams) instead, which is more precise because ingredients like flour can pack differently depending on how they're scooped. When following a recipe written in cups or fluid ounces, converting to milliliters first can help if you're using a metric kitchen scale or measuring jug.
Example
1 mL equals 0.061023744 in³. For scale, that's about 0× a standard 1-liter water bottle (1 L, or 1000 mL).
Frequently Asked Questions
How many Cubic Inches are in 1 Milliliter?
1 Milliliter (mL) equals exactly 0.061023744 Cubic Inches (in³).
Why is a US gallon smaller than a UK gallon?
The US kept the older English wine gallon (231 cubic inches, about 3.785 L) after independence, while the UK redefined its gallon in 1824 based on the volume of 10 pounds of water (about 4.546 L) — the two countries never reconciled the difference, so today "gallon" means two different volumes depending on where you are.
How many milliliters are in a US cup?
One US cup equals exactly 236.5882365 milliliters, though many recipes and kitchen tools round this to 240 mL for simplicity.
Is a cubic centimeter the same as a milliliter?
Yes — one cubic centimeter (cm³ or cc) is exactly equal to one milliliter by definition, which is why medical dosing is often labeled in either unit interchangeably.
