An accurate way to measure the air in a football is to measure the air pressure in the football. Then, using Boyle's Law, P(1) x V(1) = P(2) x V(2), you can compute the volume of air, at standard pressure. This will give you a quite accurate answer, since temperature really doesn't change things here. Note that, according to Boyle's Law, the higher the pressure in the football, the more air there is inside. This coincides with what you'd expect.

A hygrometer.
Humidity is a measure of the amount of water vapor present in the air compared to the maximum amount the air can hold at a specific temperature. It is often expressed as a percentage with higher values indicating air that is closer to being saturated.
No, a hygrometer measures humidity; the amount of water in the air.
Humidity is the amount of water vapor present in the air. It is a measure of the water content in the atmosphere, indicating how much moisture the air can hold. Low humidity means there is a lack of water vapor in the air, while high humidity means there is a higher amount of water vapor present.
Humidity is the term used to measure the amount of moisture in the air.
Relative humidity is a measure of the amount of water vapor in the air. It represents the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a specific temperature, expressed as a percentage.

Relative humidity is a measure of the amount of water vapor content in the air compared to the maximum amount of water vapor that the air can hold at a specific temperature. It is expressed as a percentage and provides insight into how close the air is to being saturated with moisture.
The measure of the amount of water vapor in the atmosphere is called humidity. It is typically expressed as relative humidity, which is the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a specific temperature.
