## How long is a jiffy?

Harrison, the time it takes for light to travel one fermi, which is approximately the size of a nucleon.

One fermi is 10−15 m, so a jiffy is about 3 × 10−24 seconds.

It has also more informally been defined as “one light-foot”, which is equal to approximately one nanosecond..

## What are the 7 basic units of measurement?

The units and their physical quantities are the second for time, the metre for measurement of length, the kilogram for mass, the ampere for electric current, the kelvin for temperature, the mole for amount of substance, and the candela for luminous intensity.

## What are the units of measurement from smallest to largest?

In order from smallest to largest, they rank: millimeter (mm), centimeter (cm), decimeter (dm), and meter (m). These are all common units of length in the metric system, which is a decimal measuring system. It is a system based on the meter, liter, and gram as units of length, capacity, and weight or mass.

A zeptosecond is a trillionth of a billionth of a second (10^-21 seconds). This is the greatest accuracy of time determination ever achieved, as well as the first absolute determination of the timescale of photoionization.

## What are 2 bytes called?

nibbleIn computing, a nibble (occasionally nybble or nyble to match the spelling of byte) is a four-bit aggregation, or half an octet. It is also known as half-byte or tetrade. In a networking or telecommunication context, the nibble is often called a semi-octet, quadbit, or quartet.

## Which unit is largest?

Answer and Explanation: Kilometer (Km)is the largest unit of metric measurement. It is mainly used to measure the length (distance) of various spaces, such as the distance…

## How many cm are in a ruler?

30 centimetersA standard ruler is 12-inches long and 30 centimeters in length. It is likely your ruler will state “inches” or “cm” to make it easier to tell which side is which. Each of these measurements has a perpendicular line to denote where this measurement falls on the ruler. They are the longest lines on the ruler.
