Convert Planck lengths to inches

Explanation

From this page you can convert Planck lengths to inches (or ℓ_P to in) simply, by using the application above.

In case you are wondering, to convert from Planck lengths to inches you need to multiply by 6.3632 × 10^-34. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 ℓ_P≈6.3632 × 10^-34 in

Planck lengthsℓ_P

dimension	length
symbol	ℓ_P

The Planck length (ℓ_P) is a unit of length used in theoretical physics.

Definition of the Planck length

It is defined by taking the square root of the reduced Planck constant times the gravitational constant divided by the speed of light cubed.

Value

One Planck length is equal to 1.616255 × 10⁻³⁵ meters. In this converter we use this exact value even though it is an approximation.

Equivalences

The Planck length is a minuscule unit of measure, even the diameter of atoms is expressed in septillions of Planck lengths. Fortunately, we have the power of exponent on our side.

The diameter of a proton is approximately 6.1871×10¹⁹ Planck lengths.
A giraffe would be 3.5267×10³⁵ Planck lengths tall.
The observable universe is approximately 5.4447×10⁶¹ Planck lengths.

The inch (in, '') is a unit of length in the international mass and length units.

Definition of the inch

One inch is defined as ¹⁄₃₆ of a yard.

From the Weights and Measures Act of 1985: Measurement of length

Value in terms of the SI

One inch is equivalent to 25.4 millimeters.

History

The unit's name is derived from the Roman word uncia meaning twelfth. The inch is associated with the width of a human thumb.

Today, the unit is used in the United States, Canada and the United Kingdom. And internationnaly to specify the size of display screens and the diameter of wheel rims.

Equivalences

One inch is also equivalent to:
