How much is one inch of water a week?

Yesterday, I spent about 2-3 hours searching online about the plants in my garden and how much to water it. I realized that all of the plants required about 1 inch of water per week.
That was when I started my hunt on just exactly how much is 1 inch of water. First of all, why is it per week? Does this mean you only water once a week? How’s anyone going to know who much is 1 inch w/o some additional tools? Why can’t they say something like, 2-3 times a week for 15 minutes using medium water pressured hose or something.
Anyways, after much reading, I realized that I needed to mulch. Basically, it’s up for me to gauge how much water I need depending on weather, soil conditions, etc. This is why noone can tell you. But there are some tips you can use.
For example, 1 square foot = 0.62 gallons of water. Also, if the top 1 1/2 inch of soil is dry, then it’s time to water. To see if the soil is moist, you can grab a bunch in your hand, form it into a ball, if it falls apart, it’s too dry.
Another thing I learned was that it’s better to water deeply than to water every day. You want to make sure that the water goes down to all the roots, but not too much down because then the water will carry all the nutrients down into the ground. Important if you have a square foot garden.
So, I put the mulch in, and I’m thinking maybe every 2-3 days I"ll check and see how it goes. The good thing is that there are 2 squares w/o mulch so it will give me an idea of just how fast the soil is getting dry between the non-mulch square and mulched square.
