Metric Prefixes Quiz

A metric prefix that indicates a multiplier of 1000 (10^3).

A metric prefix that indicates a multiplier of 1,000,000 (10^6).

A metric prefix that indicates a multiplier of 0.001 (10^-3).

A metric prefix that indicates a multiplier of 0.000001 (10^-6).

A metric prefix that indicates a multiplier of 1,000,000,000,000 (10^12).

Metric prefixes are used to indicate multiples or submultiples of base units. For example, 'kilo' (k) indicates 1000 times the base unit, while 'milli' (m) indicates 1/1000th of the base unit.

A multiplier is a number used to multiply a base unit to obtain a larger or smaller unit. The multiplier is expressed as a power of 10. For example, kilo (k) has a multiplier of 10^3, which means it scales the base unit by 1000.

The symbol associated with a metric prefix is a single letter used to represent the prefix. For example, the symbol for 'kilo' is 'k', the symbol for 'mega' is 'M', and the symbol for 'micro' is 'μ'.

Metric prefixes are used across different fields of science and engineering to express quantities conveniently. By using prefixes like 'kilo' for thousands or 'micro' for millionths, we can avoid writing long numbers and make calculations easier.

Larger prefixes, like 'tera' (T) and 'giga' (G), are often used to represent large quantities like memory in computers or data transfer rates. Smaller prefixes, like 'milli' (m) and 'micro' (μ), are used to represent small quantities like the size of a cell or the wavelength of light.

To convert meters per second (m/s) to kilometers per hour (km/h), multiply the value in m/s by 3.6.

1 kilometer (km) is equal to 1000 meters (m).

1 hour (h) is equal to 3600 seconds (s).

The general formula for converting m/s to km/h is: km/h = m/s * 3.6

This conversion factor arises from the relationships between the units of length and time.
