Where are the 16th on a tape measure?
A standard tape measure in the United States uses inches as the base for measurement with sixteen tick marks in between each inch marker. The smallest tick marks denote the odd numbered sixteenth marks such as 1/16, 3/16 up to 15/16.
How many inches is 1/16th of an inch?
In this case, there are 16 units of smaller quantity (1/16 inch) in one unit of the larger quantity. Multiply the larger-quantity amount by the number of smaller units per unit of the larger quantity. Multiplying 16 by 0.5 gives you 8, so 8/16 equals 0.5 inches.
Where is the 1/4 on a measuring tape?
To read 1/2-inch measurements, locate the second-longest mark between the longer inch marks. For 1/4-inch marks, look halfway between the 1/2-inch marks. You can read smaller fractions of an inch the same way. Most tapes will label the fractions to make finding them easier.
