# 11/16" to mm - SAE to Metric Calculator

Do you need to convert 11/16 inch to mm?

11/16 inch = 17.4625 mm

If you're curious how we got that answer, here's the 11/16" to mm formula:

11 ÷ 16 × 25.4 = 17.4625 mm

0.6875 × 25.4 = 17.4625 mm

To convert 11/16 inch to mm, divide 11 by 16 to convert the fraction to a decimal. Then, multiply that by 25.4 since there are 25.4 millimeters in one inch.

That's the formula that our calculator uses to find that 11/16 inch to millimeters is 17.4625 mm.

## How to Convert SAE to Metric

SAE, or standard, and metric sockets, wrenches, and fasteners are both commonly used, and the difference between them is significant. Before we cover how to convert SAE to metric, it’s important to understand what these terms actually mean.

SAE stands for Society of Automotive Engineers,^{[1]} and is based on standard imperial and U.S. customary measurements. It’s based on measurements in inch fractions and is most commonly used in the United States.

Metric sizes are used worldwide, and sockets and screws are primarily measured in millimeters.

You can use the chart below to convert an SAE size to metric, but you can also do the conversion by hand in a few easy steps.

### Step One: Convert the Fraction to Decimal

The first step is to convert the inch fraction to a decimal. You can do this by treating the fraction as a division problem and solving.

For instance:

1/4″ = 1 ÷ 4 = 0.25″

### Step Two: Convert to Millimeters

The next step is to multiply the inch decimal by 25.4 to convert it to millimeters. This is the key step for converting SAE to metric.

0.25″ × 25.4 = 6.35 mm
