Units explained
Ton (assay) (US)
The assay ton (US) equals about 29.167 grams, a mining-assay convenience unit.
Devised so an assay sample's metal in milligrams reads as troy ounces per short ton.
Ore assaying and metallurgy.
Adopted in assay laboratories to simplify ore-grade calculation.
Hectogram
A hectogram (hg) equals 0.1 kilogram, or 100 grams.
From the SI prefix 'hecto-' (from Greek 'hekaton', hundred).
Common in continental European food retail, especially Italy ('etto').
The hecto- prefix dates to the original metric system of 1795.
Ton (assay) (US) to Hectogram conversion formula
The relationship between tons (assay) (us) and hectograms:
To convert tons (assay) (us) to hectograms, multiply the value in tons (assay) (us) by 0.2916667. To reverse, multiply hectograms by 3.4285710367.

Step-by-step: convert tons (assay) (us) to hectograms
- Write down the value in tons (assay) (us) (AT).
- Multiply that value by the factor 0.2916667.
- The product is the equivalent value in hectograms (hg).
- To reverse, multiply the hectogram value by 3.4285710367.
Worked examples
Example 1 — Convert 1 AT to hg:
1 × 0.2916667 = 0.2916667 hg
Example 2 — Convert 100 AT to hg:
100 × 0.2916667 = 29.16667 hg
Real-world example — Children's height milestones
A 150-ton (assay) (us)-tall child measures a value in hectograms that's commonly used for theme-park ride height requirements when travelling between countries that use different measurement units.
150 AT × 0.2916667 = 43.750005 hg
Real-world example — Body height conversion
You enter your height as 180 tons (assay) (us) into an international job or visa application. The form then asks for the same value in hectograms — converting between these adjacent units is one of the most-used length conversions globally.
180 AT × 0.2916667 = 52.500006 hg
Real-world example — Furniture and large objects
A 72-ton (assay) (us) piece of furniture converts to a value in hectograms that's easier to mentally compare with room dimensions. This is the typical workflow when shopping internationally and product specs use a different unit than your room measurements.
72 AT × 0.2916667 = 21.0000024 hg
