Units explained
Stone (US)
A less common US definition of the stone, about 5.67 kilograms.
A variant stone weight used in some historical US trade.
Rare; appears mainly in historical or specialized contexts.
Derived from older English stone weights that varied by commodity.
Earth's Mass
The Earth mass (M(E)) is about 5.976E24 kg.
Adopted as a convenient unit for the masses of terrestrial planets.
Astronomy and planetary science.
Refined over centuries since Cavendish first 'weighed the Earth' in 1798.
Stone (US) to Earth's Mass 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 stones (us) and earth's mass:

Step-by-step: convert stones (us) to earth's mass
- Write down the value in stones (us) (st).
- Multiply that value by the factor 9.487792e-25.
- The product is the equivalent value in earth's mass (M⊕).
- To reverse, multiply the earth's mass value by 1.053986e+24.
Worked examples
Example 1 — Convert 1 st to M⊕:
1 × 9.487792e-25 = 9.487792e-25 M⊕
Example 2 — Convert 100 st to M⊕:
100 × 9.487792e-25 = 9.487792e-23 M⊕
Real-world example — Adult height conversion
A 1.8-stone (us)-tall person measures a value in earth's mass that converts the height to the unit favoured by American forms, schools, or driver's licences. This is daily routine for anyone living between metric and imperial systems.
1.8 st × 9.487792e-25 = 1.707803e-24 M⊕
Real-world example — Fabric purchase length
Two stones (us) of fabric equals a value in earth's mass essential for tailors and textile buyers sourcing material from international suppliers that quote in different units.
2 st × 9.487792e-25 = 1.897558e-24 M⊕
Real-world example — Maritime depth conversion
A 10-stone (us) sounding depth converts cleanly into earth's mass. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.
10 st × 9.487792e-25 = 9.487792e-24 M⊕
