Kan to Metric Tons (kan to t)

1 kan equals 0.00375 metric tons exactly.

1 kan = 0.00375 metric tons

How to convert kan to metric tons

To convert kan to metric tons, multiply the number of kan by 0.00375. This factor is exact. To go the other way, multiply metric tons by 266.6666667 (rounded).

metric tons = kan × 0.00375

Example: 10 kan = 0.0375 metric tons.

About these units

Kan (kan)

JapaneseTraditional unit (still used in some regions)

1,000 monme, exactly 3.75 kg. A traditional Japanese weight unit.

Long before it was a weight, the kan was a way to carry money: roughly a thousand copper coins strung together through their square holes. In China a bundle of this kind was recognised as a currency unit, and the mass unit came afterward, based on what a thousand such coins weighed.

Japan inherited both ideas. The kan equals 1,000 monme, and Edo-period measures averaged about 3.736 kg, drifting a little above 3.75 kg in the late Edo period. The Weights and Measures Act of 1891 ended the variation by defining the kan as 15/4 kg, exactly 3.75 kg, about 8.27 pounds. That is the figure used here.

The 1891 act made the shaku and the kan the foundation of the national system. Metric became the legal standard in 1924 and the sole one from 1959, leaving the kan as a non-statutory unit whose trade use is penalised, though shaved-ice blocks are still sold as kan-me.

1 kan = 3.75 kilograms (exactly).

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).
