Slugs to Metric Tons (slug to t)

1 slug equals 0.01459390294 metric tons (rounded).

1 slug = 0.01459390294 metric tons

How to convert slugs to metric tons

To convert slugs to metric tons, multiply the number of slugs by 0.01459390294. The factor is rounded to 10 significant digits. To go the other way, multiply metric tons by 68.52176586 (rounded).

metric tons = slugs × 0.01459390294

Example: 10 slugs = 0.1459390294 metric tons.

About these units

Slug (slug)

US customaryTraditional unit (still used in some regions)

About 14.594 kg. The US engineering unit of mass: the mass that accelerates at 1 ft/s² under a force of 1 pound-force.

Physics teachers in feet-and-pounds countries face an awkward fact: the pound is used both as a unit of mass and as a unit of force. The slug removes the ambiguity. It is the mass that a force of one pound-force accelerates at one foot per second squared, so that one slug equals one lbf s squared per foot. The British physicist Arthur Mason Worthington is credited with coining the name before 1900, taking it in the sense of a block of metal rather than the mollusc. An older name for it was the geepound.

One slug is about 14.594 kg, which is roughly 32.17 avoirdupois pounds, and the figure used here follows standard gravity, the international foot and the avoirdupois pound. An object of one slug weighs about 143.1 newtons at the Earth's surface. The unit belongs to the gravitational foot-pound-second system and stayed mostly in American engineering while a 1928 textbook noted that no special name was really needed. Its inch-based cousin, 12 slugs, is jokingly called a blob or slinch.

1 slug = 14.59390294 kilograms (approximately).

Metric Ton (t)

Metric (SI)Current unit

1,000 kilograms (about 2,204.6 lb), also spelled tonne. Used for cargo, grain and vehicle weights outside the US.

Barrels gave the tonne its name. The word goes back to a Germanic root for a large cask, the tun, and a full tun could easily weigh around a tonne. In English this became ton; the spelling tonne has been used in France since 1842, where it replaced the older tonneau, and pre-metric French tonnes were 2,000 livres, about 979 kg. Once the metric system took hold, the tonne was fixed at 1,000 kilograms, which is the mass of roughly a cubic metre of water.

The unit is accepted for use with the SI, and its symbol is a lowercase t with no period. Because it sits close to the old English ton, the two get confused: the short ton used in the US is about 10 percent lighter than a tonne, while the long ton differs by less than 2 percent. NIST calls the unit the metric ton, and the spelling tonne is rare in the US. Very large quantities are stated in prefixed forms such as the megatonne, which equals a teragram. In explosives, a tonne of TNT is taken as about 4.2 gigajoules.

1 metric ton = 1,000 kilograms (exactly).
