The measurements of physical quantities are expressed in terms of units, which are standardized values. For example, the length of a race, which is a physical quantity, can be expressed in meters (for sprinters) or kilometers (for long distance runners).
Feb 20, 2022 · A conversion factor is a ratio expressing how many of one unit are equal to another unit. For example, there are 12 inches in 1 foot, 100 centimeters in 1 meter, 60 seconds in 1 minute, and so on. In this case, we know that there are 1,000 meters in 1 kilometer. Now we can set up our unit conversion.
1 kilometer = 1, 000 meters. To convert larger units to smaller units we multiply the number of larger units by the green conversion factor for the appropriate smaller units. Example: Converting meters to centimeters: 1 meter = 100 centimeters. 11 meters = 11 × 100 = 11 00 centimeters.
Apr 25, 2024 · 1 Kilometer Per Hour (km/h) = 0.27778 Meters per Second (m/s) One kilometer per hour (km/h) is equivalent to approximately 0.27778 meters per second (m/s), making it a straightforward unit for converting larger scale speeds to finer measurements.
Metric systems have the advantage that conversions of units involve only powers of 10. There are 100 centimeters in a meter, 1000 meters in a kilometer, and so on. In nonmetric systems, such as the system of U.S. customary units, the relationships are not as simple—there are 12 inches in a foot, 5280 feet in a mile, and so on.
