How Much is X Amount of Rain?

1/100” is the least amount of measurable accumulation. This amount slightly wets a surface area but does not create puddles.

1/100” is a light shower for 2 to 5 minutes or a drizzle for two hours.

1/10” is a light rain for 30 to 40 minutes, moderate rain for 10 minutes, or a heavy rain for 5 minutes. Small puddles are formed but will quickly disappear.

1/4” is a light rain for 2 to 3 hours, moderate rain for 30 to 60 minutes, or a heavy rain for 15 minutes forming many puddles that do not disappear quickly.

1/2” is moderate rain for 1 to 2 hours or heavy rain for 30 to 45 minutes forming deep standing puddles that remain for a long period of time.
