Attogram

What is a attogram?

An attogram (ag) equals 10^-21 kilogram.

Origin of the attogram

From the SI prefix 'atto-' (from Danish 'atten', eighteen).

Where it is used

Frontier nanoscience and single-molecule mass detection.

When and where it was developed

The atto- prefix was adopted by the CGPM in 1975.

Scientific / Atomic

MeV/c2

What is a mev/c2?

MeV/c^2 expresses mass through mass-energy equivalence, E = mc^2; 1 MeV/c^2 is about 1.783E-30 kg.

Origin of the mev/c2

Derived from Einstein's mass-energy relation, convenient for particle masses.

Where it is used

Particle physics, where masses are stated in MeV/c^2 or GeV/c^2.

When and where it was developed

Came into use with relativistic particle physics in the 20th century.

Attogram to MeV/c2 conversion formula

The relationship between attograms and mev/c2:

1 ag = 5.609589e+8 MeV/c²
1 MeV/c² = 1.782662e-9 ag

To convert attograms to mev/c2, multiply the value in attograms by 5.609589e+8. To reverse, multiply mev/c2 by 1.782662e-9.

How to use this converter

Type a value into the calculator. The result in mev/c2 updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the MeV/c2 to Attogram converter for the reverse direction.

Step-by-step: convert attograms to mev/c2

  1. Write down the value in attograms (ag).
  2. Multiply that value by the factor 5.609589e+8.
  3. The product is the equivalent value in mev/c2 (MeV/c²).
  4. To reverse, multiply the mev/c2 value by 1.782662e-9.

Worked examples

Example 1 — Convert 1 ag to MeV/c²:
1 × 5.609589e+8 = 5.609589e+8 MeV/c²

Example 2 — Convert 100 ag to MeV/c²:
100 × 5.609589e+8 = 5.609589e+10 MeV/c²

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 attograms can be re-expressed in mev/c2 for direct comparison with another instrument's calibration data sheet.

800 ag × 5.609589e+8 = 4.487671e+11 MeV/c²

Real-world example — Molecular dimensions

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

2 ag × 5.609589e+8 = 1.121918e+9 MeV/c²
