An hour is a unit of measurement. A ratio is a comparison of similar things. You can use hours within a ratio showing something over a measurement of time. For example as speed (25 miles/kilometers per hour) or hourly wages ($7.25 per hour).
An hour can also be a measurement of Right Ascension. This is a measure timing the passage of objects in the sky across the meridian as the Earth rotates. RA is measured in hours, minutes, and seconds.
interval
A ratio level of measurement is the highest level of measurement that includes all the properties of nominal, ordinal, and interval levels, with the addition of a true zero point. This means that in ratio measurement, both differences and ratios of measurements are meaningful. Examples include height, weight, and temperature in Kelvin, where a value of zero indicates the absence of the quantity being measured. This level allows for a wide range of statistical analyses due to its comprehensive nature.
No, it is nominal.

Ratio
Year of birth is interval level of measurement; age is ratio.
It is a ratio scale of measurement.
interval
Three basic levels of measurement are nominal, ordinal, and interval/interval-ratio.
Three basic levels of measurement are nominal, ordinal, and interval/interval-ratio.
Ratio. It has a true zero.
Nominal Scale < Ordinal< Interval < Ratio
Questionnaires typically use nominal, ordinal, interval, or ratio levels of measurement. The level of measurement chosen depends on the specific type of data being collected and the research objectives.
It is ratio; it has a natural zero and is numerical data.
It is an interval scale. It is not a ratio scale, the next higher level, because the zero is arbitrary and not unique from one calendar to another.
