The metric system is a decimal system of measurement based on the meter, an international standard for length. One of the fundamental units in the metric system is the centimeter (cm), which is defined as one hundredth of a meter. Another metric unit frequently used for measuring length is the millimeter (mm), which is one thousandth of a meter.
To convert 137 mm to cm, you can simply divide the value of 137 mm by 10. This is because 1 cm is equivalent to 10 mm.
137 mm / 10 = 13.7 cm
Therefore, 137 mm is equal to 13.7 cm.
Length conversion plays a crucial role in various practical applications, such as:
Engineering and Manufacturing: Engineers and manufacturers use precise length measurements to ensure the accuracy and fit of components.
Medical and Healthcare: Medical professionals rely on accurate length measurements for dosage calculations, surgical procedures, and diagnostic imaging.
Construction and Architecture: Architects and construction workers use length measurements to design and build structures according to specific plans.
Textile and Fashion: Clothing designers and manufacturers use length measurements to determine fabric requirements and ensure proper fit for garments.
Sports and Recreation: Athletes, coaches, and referees use length measurements to measure distances, track performance, and determine field dimensions.
1. Identify the Units: Determine the units of the length measurement you need to convert (e.g., mm).
2. Convert to Base Units: If the given units are not meters (m) or centimeters (cm), convert the length to meters first. For example, to convert millimeters (mm) to meters, divide by 1000 (mm/1000 = m).
3. Convert to Target Units: If the target units are not meters or centimeters, convert the length from meters to the target units. For example, to convert meters (m) to centimeters (cm), multiply by 100 (m x 100 = cm).
