The metric system, or International System of Units (SI), is a decimal system based on units of ten. It uses base units like meters (for length), grams (for mass), and liters (for volume). The imperial system, primarily used in the United States, employs units like inches, feet, yards, and miles for length, ounces and pounds for weight, and gallons for liquid volume. These systems utilize different scales and relationships between units, necessitating conversion factors for transitioning between them.
The Conversion Factor: Centimeters to Inches
The fundamental relationship between centimeters and inches is the conversion factor. One inch is approximately equal to 2.54 centimeters. This means that to convert centimeters to inches, we divide the number of centimeters by 2.54. Conversely, to convert inches to centimeters, we multiply the number of inches by 2.54. This factor is crucial for all centimeter-to-inch conversions.
Calculating 98cm into Inches
Now, let's apply this knowledge to convert 98 centimeters into inches. Using the conversion factor (1 inch ≈ 2.54 cm), we perform the following calculation:
98 cm / 2.54 cm/in ≈ 38.58 in
Therefore, 98 centimeters is approximately equal to 38.58 inches. It's important to note that this is an approximation because the conversion factor is itself an approximation. The actual value might vary slightly depending on the level of precision required.

98cm into Inches: A Beginner's Guide to Metric-Imperial Conversion
Have you ever bought clothes online only to find they fit strangely? Or maybe you're following a recipe that uses centimeters while your measuring cups are in inches? These are common scenarios where understanding how to convert between metric (like centimeters) and imperial (like inches) units becomes crucial. This article will guide you through converting 98 centimeters into inches, explaining the process step-by-step in a way that's easy to understand, even if you're completely new to unit conversion.
I. Understanding the Units
Before we dive into the conversion, let's understand what centimeters and inches are.
Centimeter (cm): This is a unit of length in the metric system. Think of it as a small unit, roughly the width of your little finger. The metric system is based on powers of 10, making conversions relatively straightforward.
Inch (in): This is a unit of length in the imperial system, a system still widely used in the United States and a few other countries. An inch is roughly the length of the top segment of your thumb. The imperial system uses less logical relationships between its units, making conversions slightly more complex.
II. The Conversion Factor: The Bridge Between Systems
To convert between centimeters and inches, we need a conversion factor – a number that tells us the relationship between the two units. This factor is approximately 2.54 centimeters per inch. This means that 1 inch is equal to 2.54 centimeters. Think of it like this: if you line up 2.54 centimeter rulers end-to-end, they would be exactly as long as a single inch ruler.
III. Performing the Conversion: From Centimeters to Inches
Now let's convert 98 centimeters to inches. Since 1 inch is equal to 2.54 centimeters, we can set up a simple equation:
`98 cm (1 inch / 2.54 cm) = X inches`
Notice how we've arranged the conversion factor (1 inch / 2.54 cm) so that the "cm" units cancel out, leaving us with only "inches." This is a crucial step in ensuring our conversion is correct.
Now, let's do the math:
`98 cm / 2.54 cm/inch ≈ 38.58 inches`
Therefore, 98 centimeters is approximately equal to 38.58 inches.
