Frequently asked questions about 2 inches
What things are 2 inches long?
An AA battery is nearly exact at 1.96 inches, two US quarters side by side span 1.91 inches, and a golf ball is 1.68 inches across. Line any of them up against the ruler to see how close they land.
How long is 2 inches compared to a finger?
About two thumb-widths, or the two outer segments of an adult index finger. Fingers vary far too much for precision, though — the on-screen ruler is calibrated to your exact display.
Is 2 inches the same as 5 centimeters?
Almost: 2 inches is 5.08 centimeters. If a recipe or spec calls for 5 cm, it is asking for a hair less than 2 inches.
How can I measure 2 inches without a ruler?
A AA battery plus a quarter stacked edge to edge come within a twentieth of an inch. Or calibrate this page once and the ruler in your pocket is the screen itself.
