These common values provide a quick check for lb to metric-tonne conversions.
1 lb = 0.00045359237 t.
1,000 lb ≈ 0.453592 t.
2,000 lb ≈ 0.907185 t.
2,204.6226 lb = 1 metric tonne.
To convert pounds to tonnes, multiply the weight in pounds by 0.00045359237. This result is in metric tonnes, where one tonne equals exactly 1,000 kilograms.
tonnes = pounds × 0.00045359237Suppose a material load weighs 5,000 pounds. Multiply 5,000 by 0.00045359237:
5,000 × 0.00045359237 = 2.26796185 tonnesSo 5,000 pounds equals about 2.267962 metric tonnes when shown to six decimal places.

A metric tonne is not the same as a US short ton. One metric tonne equals 1,000 kilograms, while one US short ton equals 2,000 pounds. This is why 2,000 pounds converts to about 0.907185 metric tonnes rather than exactly 1 tonne.
An imperial long ton is also different from a metric tonne. A long ton equals 2,240 pounds. When converting pounds to tonnes on this page, the output always means metric tonnes.
The international avoirdupois pound is defined as exactly 0.45359237 kilograms. Since one metric tonne is exactly 1,000 kilograms, dividing 0.45359237 by 1,000 gives exactly 0.00045359237 tonne per pound.
Weight conversions are useful when supplier data, equipment limits, aggregate quantities or imported specifications use pounds while project records use metric tonnes. Keeping the units explicit helps prevent confusion between pounds, kilograms, short tons and metric tonnes.
Concrete, cement, sand, gravel and aggregate may be quoted by weight in different unit systems. This converter changes only the weight unit. It does not convert volume to mass because that requires a material density. For density-based calculations, use a calculator that includes the correct density for the material being measured.
1,000 pounds equals 0.45359237 metric tonnes.
One metric tonne is approximately 2,204.62262185 pounds. For the reverse calculation, use a dedicated Tonnes to Pounds converter.
For other weight conversions, use the Pounds to Kilograms, Pounds to Grams, Pounds to Ounces, Pounds to Short Tons and Tonnes to Pounds converters.
