A 2-column table with 3 rows titled Units of Length. Column 1 is labeled Customary System Units with entries 1 inch, 1 foot, 1 mile. Column 2 is labeled Metric System Units with entries 2.54 centimeters, 0.3048 meters, 1.61 kilometers.

To convert meters to inches, you can use the following conversion factors:

1 meter = 100 centimeters
1 inch = 2.54 centimeters

First, we convert meters to centimeters and then centimeters to inches. Since we want to convert 4 meters to inches:

1. Convert meters to centimeters: \[ 4 \text{ meters} \times 100 \text{ centimeters/meter} = 400 \text{ centimeters} \]

2. Convert centimeters to inches: \[ 400 \text{ centimeters} \div 2.54 \text{ centimeters/inch} \approx 157.48 \text{ inches} \]

So, 4 meters is approximately 157.48 inches.

Using your format: a = 4
b = 0 (not used)
c = 157.48
d = inches
