The **Planck time** is the **time** it would take a photon travelling at the speed of light to across a distance equal to the **Planck length**. This is the ‘quantum of **time**‘, the smallest measurement of **time** that has any meaning, and is equal to 10^{–}^{43} seconds.

Then, How big is a Yoctometer?

Yoctometer is the smallest length unit under the SI international Standard of Units, and represents **1 x 10**^-24 meters.

Considering this, How big is a quark? While the size of protons and neutrons is of the order of a Fermi (10^{−}^{15} m), the size of **quarks** is ~10^{−}^{18} m. It is deemed that **quarks** are composed of smaller particles – preons.

A micrometer, also called a micron, is one thousandtimes **smaller than** millimeter. It is equal to 1/1,000,000th(or one millionth of meter).

**How far does light travel in a Planck time?**

In quantum mechanics, the **Planck time** ( t _{P}) is the unit of **time** in the system of natural units known as **Planck** units. A **Planck time** unit is the **time** required for **light** to **travel** a **distance** of 1 **Planck** length in a vacuum, which is a **time** interval of approximately 5.39 × 10^{−}^{44} s.

The **yoctometre** (International spelling as used bythe International Bureau of Weights and Measures; SI symbol: ym) or**yoctometer** (American spelling) is an SI measure of lengththat is equal to 10 ^{−}^{24} (yocto) of ametre. It is the smallest named subdivision of the metre in the SIbase unit of length.

**What is the size of a Femtometer?**
