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.
Lunar Mass (Moon)
The lunar mass (M(L)) is about 7.342E22 kg.
The mass of the Moon, used as a unit for natural satellites.
Planetary science, for comparing moons of the solar system.
Determined from the Moon's orbit and modern spacecraft tracking.
Ton (assay) (US) to Lunar Mass (Moon) conversion formula
Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.
The relationship between tons (assay) (us) and lunar mass (moon):
To convert tons (assay) (us) to lunar mass (moon), multiply the value in tons (assay) (us) by 3.972578e-25. To reverse, multiply lunar mass (moon) by 2.517257e+24.

Type a value into the calculator. The result in lunar mass (moon) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Lunar Mass (Moon) to Ton (assay) (US) converter for the reverse direction.
Step-by-step: convert tons (assay) (us) to lunar mass (moon)
- Write down the value in tons (assay) (us) (AT).
- Multiply that value by the factor 3.972578e-25.
- The product is the equivalent value in lunar mass (moon) (M☾).
- To reverse, multiply the lunar mass (moon) value by 2.517257e+24.
Worked examples
Example 1 — Convert 1 AT to M☾:
1 × 3.972578e-25 = 3.972578e-25 M☾
Example 2 — Convert 100 AT to M☾:
100 × 3.972578e-25 = 3.972578e-23 M☾
Real-world example — Hardware-scale dimensions
A 10-ton (assay) (us) fastener or component is about as long as a thumbnail. Mechanics and DIY enthusiasts convert between tons (assay) (us) and lunar mass (moon) daily when mixing metric and imperial tools.
10 AT × 3.972578e-25 = 3.972578e-24 M☾
Real-world example — Postcard and small-object dimensions
A postcard is about 5 tons (assay) (us) wide. Converting to lunar mass (moon) is essential for international postal addressing forms that ask for dimensions in different units across countries.
5 AT × 3.972578e-25 = 1.986289e-24 M☾
Real-world example — Ruler-scale measurements
A 30-ton (assay) (us) school ruler converts cleanly to lunar mass (moon) — useful when buying a desk accessory from a retailer whose product specs use a different unit.
30 AT × 3.972578e-25 = 1.191773e-23 M☾
