# Which measurement is longest?

## Which measurement is longest?

Kilometers are the longest unit of metric measurement. The abbreviation for kilometers is ‘km”.

What is the longest distance of measurement?

One gigaparsec (Gpc) is one billion parsecs — one of the largest units of length commonly used. One gigaparsec is about 3.26 billion ly, or roughly 114 of the distance to the horizon of the observable universe (dictated by the cosmic background radiation).

### What is the longest measuring tool?

The longest tape measure in the world is gold plated and was made in 1956 by a surveyor and tape-maker, Justus Roe, and it measures 180 metres (600 feet)….Tape Measure

• Tape measures are rulers that are flexible and are used for measuring.
• ‘Tape measures’ are also known as ‘measuring tapes’.

What is used to measure longer length?

Measuring instruments used to measure the length. (i) To measure long distances like length and breadth of a park or field we use measuring tapes. It is 50 cm or 100 cm or 250 cm or more in length.

#### What was the shortest measurement?

What is a zeptosecond? A zeptosecond is a trillionth of a billionth of a second. That’s a decimal point followed by 20 zeroes and a 1, and it looks like this: 0.000 000 000 000 000 000 001. The only unit of time shorter than a zeptosecond is a yoctosecond, and Planck time.

What is the most accurate tape measure?

The Best Tape Measures for Precise Measurements

1. Fiskars 16-Foot Tape Measure.
2. Stanley 25-Foot by One-Inch Measuring Tape.
3. Singer ProSeries Retractable Tape Measure.
4. Swanson Tool Proscribe Tape Measure.
5. eTape16 Digital Tape Measure.

## Why does my tape measure start at 2?

The tape starts at 2 inches so that the measurement includes the portion of the case that is snug against the body when using the tape. As a result, the measurement you read on the tape automatically subtracts this 2 inches, and the number you read on the tape is exactly accurate!

Is Angstrom smaller than Fermi?

an angstrom is 10^-10 m, and is crudely on the same order of magnitude as the size of an atom. a Fermi is the smallest of three at 10^-15 m (also called a femtometer), and its length roughly describes the scale of atomic nuclei (hence it is named after the nuclear physics pioneer Enrico Fermi).

### What is longer than a fortnight?

English also has a “one-week” equivalent to fortnight: sennight. Sennight, for a “period of seven days and nights,” is archaic, supplanted by the word week.

What is the greatest measure of length?

1 km is the greatest measure of length. Step-by-step explanation: To solve this question, first we will convert all measures into same unit then by comparing them we can tell the greatest length.

#### What is the smallest measurement of length?

The metric measure units of length are based on the meter. The millimeter (mm) is the smallest metric measure of length and equals 1/1000 of a meter.

What are the units of measurement from smallest to largest?

A millimeter (mm) is the smallest. In order from smallest to largest they rank millimeter, centimeter (cm), decimeter (dm), and meter (m). These are all common units of length in the metric system.

## What is the biggest unit of measurement?

One yottabyte (abbreviated “YB”) is equal to 1,000 zettabytes and is the largest SI unit of measurement used for measuring data.
