Hint: In the metric system, centimeters (cm) and meters (m) are all distance measurements. There are 100 centimeters in each meter, which means it can be translated into meters by dividing the measurement by 100 centimeters. Through simply moving the decimal point in your calculation 2 spaces (or "position values") towards the left, you can make this conversion fast and simple. Likewise, if then you need to translate from meters to centimeters just push the decimal point 2 spaces to the right.
Complete step-by-step answer:
Meters(m) and millimeters(mm) are generally used for longitude metric measurements. The metric system is a decimal-based measurement system used by most countries around the world. The metric system is based on multiples of 10, so by multiplying and dividing you can turn meters into millimeters and vice versa very easily.
The height of a person is 1.65 meters.
As we know 1 meter = 100 cm; and 1000 mm
Thus, 1.65 m = 1.65 × 100 = 165 cm;
= 1.65 × 1000 = 1650 mm.
Hence, option B is the right answer.
Note: The meter is the unit of displacement or length of the International System of Units (SI). One meter is the distance traversed in \[1/299,792,458(3.33564095 \times {10^{ - 9}})\] of a second by a ray of electromagnetic (EM) energy through a vacuum. The meter was originally defined as one ten-millionth \[(0.0000001\;{\text{or 1}}{{\text{0}}^{ - 7}})\]of the distance, as measured on the surface of the earth in a large circle passing through Paris, France, from the north pole to the equator.
A centimeter is a measurement device used to measure an object 's length. It is also written as cm.
The distance traveled by an electromagnetic (EM) ray through a vacuum in a time interval of \[3.33564095 \times {10^{ - 12}}\] seconds is one millimeter.
