The 20 inch gauge is the norm throughout the National Weather Service. However, other agencies like the U.S. Forest Service often use the smaller gauge. The inner measuring tube of the large NWS gauge holds 2.0 inches of precipitation. The measuring tube of the small gauge holds 0.50 inch.

## How does a rain gauge work simple?

A rain gauge is really just a cylinder that catches rain. If an inch collects in the cylinder, it means an inch of rain has fallen. It’s that simple. Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside.

## Can you use a 5 gallon bucket as a rain gauge?
