理解体积和容量
体积是物质或物体占据的三维空间的测量。容量是一个密切相关的术语，指容器可以容纳的数量。这些概念在烹饪、工程和物流中至关重要。
介绍
Volume measurement quantifies the three-dimensional space within boundaries, whether solid, liquid, or gas. From measuring ingredients in cooking to calculating fuel capacity in vehicles, volume is fundamental to countless applications.
历史
Volume measurement has ancient origins in trade and agriculture. Early civilizations used containers of standard sizes for commerce. The metric system standardized volume units, with the liter becoming widely adopted for practical measurements while cubic meters serve scientific applications.
关键单位
Cubic meter (m³)
The SI unit of volume, equal to the volume of a cube with edges of one meter.
Liter (L)
Equal to 0.001 m³, the most common unit for measuring liquids in daily life.
Milliliter (mL)
Equal to 0.001 L, used for small liquid volumes and medical dosages.
Gallon (gal)
An imperial unit (3.785 L in US, 4.546 L in UK), used for fuel and large liquid quantities.
Cubic foot (ft³)
Equal to 0.0283 m³, used in construction and HVAC applications.
Fluid ounce (fl oz)
A small volume unit (29.57 mL in US, 28.41 mL in UK), used for beverages and cooking.

Volume Calculations
Cube: V = l³, Cylinder: V = πr²h, Sphere: V = (4/3)πr³Volume formulas depend on shape geometry: cubes use length cubed, cylinders use base area times height.
