Step 1: Understand the given unit of length

The given unit of length is 1 1/2 millimeters. This can also be written as 1.5 millimeters or 1 and 1/2 millimeters.

Step 2: Determine the desired unit

The first step in converting units is to determine the desired unit. In this case, we want to convert millimeters to another unit of length.

Step 3: Know the conversions rates

To convert millimeters to another unit of length, we need to know the conversion rates. In this case, 1 millimeter is equal to 0.001 meters, 0.01 centimeters, or 0.0393701 inches.

Step 4: Select the desired unit of length

Based on the given conversion rates, we can choose the unit of length we want to convert millimeters to. Let’s choose meters for this example.

Step 5: Set up the conversion equation

To convert millimeters to meters, we will use the conversion rate of 1 millimeter = 0.001 meters. This can be written as:

1.5 millimeters * (0.001 meters / 1 millimeter)

Step 6: Cancel out units

In order to convert millimeters to meters, we need to cancel out the unit of millimeters in the equation. This can be achieved by multiplying the numerator and denominator by 1 millimeter:

1.5 millimeters * (0.001 meters / 1 millimeter) * (1 millimeter / 1 millimeter)

This will give us the final equation:

1.5 millimeters * (0.001 meters / 1)

Simplifying this further, we get:

1.5 * 0.001 meters

Step 7: Solve for the value

Finally, we can solve the equation to get the converted value:

1.5 * 0.001 = 0.0015 meters

Step 8: Write the final answer

Therefore, 1 1/2 millimeters is equivalent to 0.0015 meters.

Step 9: Provide extra information

It is important to note that the conversion rate may vary depending on the unit you choose to convert millimeters to. Always double check your conversions and use the correct conversion rate for accurate results.
