Ton (assay) (US)

What is a ton (assay) (us)?

The assay ton (US) equals about 29.167 grams, a mining-assay convenience unit.

Origin of the ton (assay) (us)

Devised so an assay sample's metal in milligrams reads as troy ounces per short ton.

Where it is used

Ore assaying and metallurgy.

When and where it was developed

Adopted in assay laboratories to simplify ore-grade calculation.

Metric / SI

Nanogram

What is a nanogram?

A nanogram (ng) equals 10^-12 kilogram.

Origin of the nanogram

From the SI prefix 'nano-' (from Greek 'nanos', dwarf).

Where it is used

Molecular biology, forensics, and toxicology.

When and where it was developed

The nano- prefix entered the SI in 1960.

Ton (assay) (US) to Nanogram conversion formula

The relationship between tons (assay) (us) and nanograms:

1 AT = 2.916667e+10 ng
1 ng = 3.428571e-11 AT

To convert tons (assay) (us) to nanograms, multiply the value in tons (assay) (us) by 2.916667e+10. To reverse, multiply nanograms by 3.428571e-11.

How to use this converter

Type a value into the calculator. The result in nanograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Nanogram to Ton (assay) (US) converter for the reverse direction.

Step-by-step: convert tons (assay) (us) to nanograms

  1. Write down the value in tons (assay) (us) (AT).
  2. Multiply that value by the factor 2.916667e+10.
  3. The product is the equivalent value in nanograms (ng).
  4. To reverse, multiply the nanogram value by 3.428571e-11.

Worked examples

Example 1 — Convert 1 AT to ng:
1 × 2.916667e+10 = 2.916667e+10 ng

Example 2 — Convert 100 AT to ng:
100 × 2.916667e+10 = 2.916667e+12 ng

Real-world example — Centimeter to wavelength scale

One ton (assay) (us) equals 10 million nanograms. Physics curricula use this kind of conversion to relate everyday measurements to atomic and optical scales.

1 AT × 2.916667e+10 = 2.916667e+10 ng

Real-world example — Small-scale to atomic-scale

One ton (assay) (us) equals 10 million nanograms — useful for physics curricula that relate everyday measurements to atomic and optical scales.

1 AT × 2.916667e+10 = 2.916667e+10 ng
