Why does one inch in an official rain gauge actually only one - tenth of an inch of rain?

If the rain gauge has a 10:1 ratio as described, then the funnel on top has an area that is 10 times the cross-sectional area of the glass tube. Suppose you had a can, that has the same area opening as the funnel, then if it rains 0.5 inch that day, there will be 0.5 inches of water in the can, but if you take the water in that can and pour it into the rain gauge (with cross sectional area 1/10 of the can), that same volume of water will fill up the gauge by 5 inches.
They do this so that it is easier to read the amount of rain. If you did not have the funnel on top, it'd be harder to read how much rain there was (was it 0.1 inches or 0.15 inches for example), plus statistically a smaller opening has less of a chance of 'catching' a raindrop than the wider opening.

How do you make an improvised rain gauge?
You can improvise a rain gauge using a soda bottle. Cut the soda bottle in half. Run a line of masking tape along the height of the bottles base. Using a marker and a ruler, mark each inch or milliliter along the tape. Place the top of the bottle upside down into the base, forming a funnel. Staple in place to secure. Place the rain gauge in an open spot in your yard to catch the rain.

Why does one inch in an official rain gauge actually measure only one tenth of an inch of rain?
The inner container is tall and narrow, but 1 inch in the inner container is only 1/10 inch of rain. This makes it possible to obtain very accurate measurements--to 1/100 of an inch--of the amount of rainfall.
Why does one inch in an offical rain gauge actually measure only one tenth of an inch of rain?
Because area of the opening of the collector is ten times the area of the measuring tube (it is a funnel). This provides for more accurate measurement of small amounts of rain.
