1 AA Battery

As you are probably already aware, there are all sorts of battery sizes. While they all are rated at 1.5 volts, the size difference has more to do with how much power it can supply. That’s why power-intensive electronics, like remote-controlled cars, require larger batteries than your TV’s remote control.

AA is a common battery type. If you take an AA battery out of your children’s toys, you’ll find that it measures 48 millimeters in length, which is just 2 millimeters shy of 5 centimeters. Alternatively, you could take the widths of about 4 AA batteries to get close to 5 centimeters.

Using coins as a reference for measuring short distances can be a good idea. And if you plan on doing laundry this week, make sure you get a close look at your quarters. According to the United States Mint, a quarter measures 24.26 millimeters in diameter.

This means that placing two of them side by side will give you a collective width of 48.52 millimeters or roughly 5 centimeters. You could also use 2 $1 coins to measure slightly beyond the 5-centimeter point.

So, if you want to measure 5 centimeters, you will have to get your hands on a small-sized golf tee. If possible, you should use a single 1.5- or 2.125-inch golf tee since it will get you closer to 5 centimeters than a 2.75-inch-long tee.
