Chapter 1: Problem 31

Fill in each blank. 1 m= _________ cm

Short Answer

Expert verified
1 m = 100 cm.

Step by step solution

01

Convert Meters to Centimeters

We know that 1 meter is equivalent to 100 centimeters. This is a standard conversion factor that helps us move from one unit of measurement to another within the metric system.
02

Fill in the Blank

Based on the conversion factor, the blank should be filled with 100. Thus, 1 meter equals 100 centimeters.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Unit Conversion
Unit conversion is a process in which one unit of measurement is changed into another, helping to easily understand and compare various measures. When working within a single measurement system, such as the metric system, conversion is straightforward鈥攖hanks to its decimal-based design.
This means each unit is related by a power of ten, making calculations simple.
  • To convert larger units to smaller ones, we multiply.
  • To convert smaller units to larger ones, we divide.
The key is understanding the conversion factors, like in the case of meters to centimeters, where 1 meter is equivalent to 100 centimeters. By familiarizing yourself with these conversion factors, solving conversion problems becomes intuitive and error-free.
Length Measurement
Length measurement is a fundamental part of defining the physical world. It helps us determine how long, tall, short, or wide something is. The metric system's length units include millimeters (mm), centimeters (cm), meters (m), and kilometers (km), arranged in increasing order.
To measure length accurately, consider the following:
  • Choose the appropriate tool, such as a ruler, measuring tape, or meter stick.
  • Select the suitable unit based on the object's size. For example, centimeters for books and meters for rooms.
  • Ensure proper alignment of the tool with the object's end to prevent inaccuracies.
By mastering these practices, you will gain proficiency in taking precise length measurements, essential in everything from simple tasks to scientific research.
Metric Units
Metric units provide a universally recognized standard across various domains. They are beneficial because they rely on a base-10 system, which simplifies calculations and conversions. The most common metric units for length are:
  • Millimeters (mm): Best for very small objects, like the thickness of a coin.
  • Centimeters (cm): Commonly used for medium-length objects, like the width of a book.
  • Meters (m): Ideal for larger measurements, such as the height of a wall.
  • Kilometers (km): Used for long distances, such as between cities.
When using metric units, always be aware of the context and required level of precision. This ensures clarity and accuracy, whether in scientific settings or daily life. Remembering that every unit increase in size represents a tenfold increase from the previous unit is vital for practical applications.
