One meter is approximately equal to 39.4 inches. This conversion is derived from the fixed relationship between the metric and imperial systems. Specifically, 1 inch is defined as 2.54 centimeters, and since there are 100 centimeters in a meter, the calculation can be done as follows:

1 meter = 100 centimeters

100 centimeters / 2.54 centimeters per inch ≈ 39.37 inches

This value rounds to 39.4 inches, making it a well-established and widely accepted conversion factor. Understanding this specific metric conversion is crucial, especially for applications that may require measuring lengths in either metric or imperial units.
