Units explained

Metric / SI

Centigram

What is a centigram?

A centigram (cg) equals 0.00001 kilogram, or 0.01 gram.

Origin of the centigram

From the SI prefix 'centi-' (from Latin 'centum', hundred).

Where it is used

Used in pharmacology and analytical chemistry.

When and where it was developed

Part of the original metric system of 1795.

Scientific / Atomic

Planck Mass

What is a planck mass?

The Planck mass equals about 2.18E-8 kg, formed from the constants h-bar, c, and G.

Origin of the planck mass

Introduced by Max Planck in 1899 as part of a system of natural units.

Where it is used

Theoretical physics and quantum-gravity research.

When and where it was developed

Defined by Planck in 1899 from fundamental constants.

Centigram to Planck Mass conversion formula

Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.

The relationship between centigrams and planck mass:

1 cg = 459.4089244778 mP
1 mP = 0.00217671 cg

To convert centigrams to planck mass, multiply the value in centigrams by 459.4089244778. To reverse, multiply planck mass by 0.00217671.

How to use this converter

Type a value into the calculator. The result in planck mass updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Planck Mass to Centigram converter for the reverse direction.

Step-by-step: convert centigrams to planck mass

  1. Write down the value in centigrams (cg).
  2. Multiply that value by the factor 459.4089244778.
  3. The product is the equivalent value in planck mass (mP).
  4. To reverse, multiply the planck mass value by 0.00217671.

Worked examples

Example 1 — Convert 1 cg to mP:
1 × 459.4089244778 = 459.4089244778 mP

Example 2 — Convert 100 cg to mP:
100 × 459.4089244778 = 45940.8924477767 mP

Real-world example — Mid-micron to nanometer

3 centigrams equals 3,000 planck mass — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.

3 cg × 459.4089244778 = 1378.2267734333 mP

Real-world example — From microns to sub-micron features

One centigram equals one thousand planck mass — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.

1 cg × 459.4089244778 = 459.4089244778 mP

Real-world example — Infrared to visible-spectrum mapping

A 10-centigram thermal infrared wavelength corresponds to a much larger number in planck mass, the unit favoured for ultraviolet and visible-light specifications.

10 cg × 459.4089244778 = 4594.0892447777 mP
