Kin to Metric Tons (kin to t)

1 kin equals 0.0006 metric tons exactly.

1 kin = 0.0006 metric tons

How to convert kin to metric tons

To convert kin to metric tons, multiply the number of kin by 0.0006. This factor is exact. To go the other way, multiply metric tons by 1,666.666667 (rounded).

metric tons = kin × 0.0006

Example: 10 kin = 0.006 metric tons.

About these units

Kin (kin)

JapaneseTraditional unit (still used in some regions)

160 monme, exactly 600 g. A traditional Japanese unit of weight, equal to 600 g.

Kin is the Japanese unit that older English sources call the catty. In Japan it was defined as 160 monme, or 16 hundredths of a kan.

After the 1891 Weights and Measures Act tied the kan to exactly 3.75 kg, the kin became exactly 600 g, which is the figure used here. That makes it about 1.32 pounds, a convenient size for everyday goods bought in modest quantities, and it is still the size commonly used for loaves of bread.

Japan moved to the metric system as the sole legal system from 1959, and trade use of the kin was prohibited. The older unit remains familiar to many Japanese shoppers as a size of 600 g.

1 kin = 0.6 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).
