# What is the measurement of distance?

This section indicates, step by step, how to

**measure**short**distances**, long**distances**,**distances**in tall vegetation and horizontal and vertical**distances**in steep sloping areas. To**measure distances**in a field (for example the length and width of a field), a chain or a**measuring**tape is used.A.

### What is the standard unit of measurement for distance?

So our standard unit of measure for length in the U.S. is miles, and in the rest of the world, it is

**kilometers**. On a smaller scale, such as measuring the length of a pen, we use inches in the U.S. and centimeters in the rest of the world. Other U.S. measurements that we use for length are feet and yards.#### Why is it necessary to have a standard unit of measurement?

Transcript of THE IMPORTANCE OF**STANDARD UNITS**IN EVERYDAY LIFE. as**units of measurement**for weight, in the past.**Unit of measurement**is a definite magnitude of a physical quantity, defined and adopted by convention or by law, that is used as a**standard**for**measurement**of the same physical quantity.#### Why are standard units are used in measurements?

A**unit**of**measurement**is a definite magnitude of a quantity, defined and adopted by convention or by law, that is**used**as a**standard**for**measurement**of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the**unit**of**measurement**. For example, a length is a physical quantity.#### What is the smallest unit of time?

The jiffy is the amount of time light takes to travel one fermi (about the size of a nucleon) in a vacuum. Planck time is the time light takes to travel one Planck**length**. Theoretically, this is the smallest time measurement that will ever be possible.

B.

### What is the unit of measure for time?

A unit of time or time unit is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI), and by extension most of the Western world, is the second, defined as about 9 billion oscillations of the

**caesium atom**.#### What is the unit used to measure distance?

Astronomers use metric units, and in particular the cgs (**centimeter-gram-second**) system. The basic unit of distance is the centimeter (cm). There are 100 centimeters in a**meter**and 1000**meters**in a kilometer.#### What is the standard unit of time in the metric system?

**Metric time**is the measure of**time**interval using the**metric system**, which defines the second as the base**unit of time**, and multiple and submultiple**units**formed with**metric**prefixes, such as kiloseconds and milliseconds.#### How long is a jiffy?

The earliest technical usage for jiffy was defined by Gilbert Newton Lewis (1875–1946). He proposed a unit of time called the "jiffy" which was equal to the time it takes light to travel**one centimeter**in a vacuum (approximately 33.3564 picoseconds).
