**What is the best way to measure capacity?** The best way to measure capacity depends on the context. For batteries, it’s typically measured in Ah or Wh. In other contexts, it might be measured in volume (e.g., for tanks), weight (e.g., for containers), or other relevant units.

**How do you convert volume to capacity?** Volume and capacity are often used interchangeably, but for specific applications, you can convert volume to capacity by considering the density of the material being measured. Capacity is typically the volume multiplied by the density.

**Is calculating volume and capacity the same?** Calculating volume and capacity can be similar, but they are not always the same. Volume refers to the amount of space occupied, while capacity often relates to the maximum amount of something that can be held, which may involve factors like material density.
