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).

Type a value into the calculator. The result in attograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Attogram to Quadrans (Biblical Roman) converter for the reverse direction.

Step-by-step: convert quadranses (biblical roman) to attograms

  1. Write down the value in quadranses (biblical roman) (quadrans).
  2. Multiply that value by the factor 6.01563e+16.
  3. The product is the equivalent value in attograms (ag).
  4. To reverse, multiply the attogram value by 1.662336e-17.

Worked examples

Example 1 — Convert 1 quadrans to ag:
1 × 6.01563e+16 = 6.01563e+16 ag

Example 2 — Convert 100 quadrans to ag:
100 × 6.01563e+16 = 6.01563e+18 ag

Real-world example — Infrared to visible-spectrum mapping

A 10-quadrans (biblical roman) thermal infrared wavelength corresponds to a much larger number in attograms, the unit favoured for ultraviolet and visible-light specifications.

10 quadrans × 6.01563e+16 = 6.01563e+17 ag

Real-world example — Mid-micron to nanometer

3 quadranses (biblical roman) equals 3,000 attograms — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.

3 quadrans × 6.01563e+16 = 1.804689e+17 ag

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

One quadrans (biblical roman) equals one thousand attograms — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.

1 quadrans × 6.01563e+16 = 6.01563e+16 ag
