Picogram

What is a picogram?

A picogram (pg) equals 10^-15 kilogram.

Origin of the picogram

From the SI prefix 'pico-' (from Spanish 'pico', a small quantity).

Where it is used

Single-cell biology and ultratrace chemical analysis.

When and where it was developed

The pico- prefix entered the SI in 1960.

Scientific / Atomic

Carbon-12 Atom Mass

What is a carbon-12 atom mass?

The mass of a single carbon-12 atom is exactly 12 u by definition, about 1.9926E-26 kg.

Origin of the carbon-12 atom mass

The reference nuclide that defines the unified atomic mass scale.

Where it is used

The defining standard for the atomic mass unit.

When and where it was developed

Chosen as the mass standard by IUPAC and IUPAP in 1960-1961.

Picogram to Carbon-12 Atom Mass conversion formula

The relationship between picograms and carbon-12 atom mass:

1 pg = 5.018451e+10 C-12
1 C-12 = 1.992647e-11 pg

To convert picograms to carbon-12 atom mass, multiply the value in picograms by 5.018451e+10. To reverse, multiply carbon-12 atom mass by 1.992647e-11.

Step-by-step: convert picograms to carbon-12 atom mass

  1. Write down the value in picograms (pg).
  2. Multiply that value by the factor 5.018451e+10.
  3. The product is the equivalent value in carbon-12 atom mass (C-12).
  4. To reverse, multiply the carbon-12 atom mass value by 1.992647e-11.

Worked examples

Example 1 — Convert 1 pg to C-12:
1 × 5.018451e+10 = 5.018451e+10 C-12

Example 2 — Convert 100 pg to C-12:
100 × 5.018451e+10 = 5.018451e+12 C-12

Real-world example — Wavelengths across the spectrum

Optical and atomic-scale phenomena are routinely cross-converted between sub-micron units. A photon of wavelength 800 picograms can be re-expressed in carbon-12 atom mass for direct comparison with another instrument's calibration data sheet.

800 pg × 5.018451e+10 = 4.014761e+13 C-12

Real-world example — Molecular dimensions

The diameter of small molecular structures (around 2 picograms) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.

2 pg × 5.018451e+10 = 1.00369e+11 C-12
