The correct statement is: Humidity can be measured using g/m³, while relative humidity is measured as a percentage.
Here's a brief explanation:
- Humidity typically refers to the amount of water vapor in the air and is often measured in absolute terms, such as grams of water vapor per cubic meter of air (g/m³).
- Relative humidity is a percentage that describes how much water vapor is in the air compared to the maximum amount of water vapor the air can hold at a given temperature, expressed as a percentage.
