An inch per hour (in/h) is a unit of measurement used to describe speed or rate.
While it is part of the imperial system, it is most famously used in meteorology to measure rainfall intensity.
In the United States, rainfall intensity is typically measured in inches per hour.
If a weather report says it's raining at 1 inch per hour, that means the rain would create a one-inch layer of water if it kept falling at the same rate for a full hour.
This unit enables meteorologists to accurately describe rainfall, ranging from light showers (less than 0.10 in/h) to heavy downpours (over 1.0 in/h).
The metric system is the global standard in most countries and in scientific work, so rates given in inches per hour are usually converted to millimeters per hour (mm/h).
The conversion is exact: 1 inch per hour = 25.4 millimeters per hour.
Standardizing units this way is essential for hydrologists, climate scientists, and engineers who need to compare rainfall records and flood-risk models across regions.
While its most common use is for weather, the inch per hour unit is also perfect for measuring very slow speeds in science and industry. Some examples include:
