About the US short tons to pounds converter
US short tons occur in freight, aggregates and material orders. Check the word short in the source specification before entering a value. A metric tonne and a UK long ton have different masses, so a bare ton label is not enough to identify the factor.
One short ton is exactly 2,000 pounds, so 2 ton (US) is 4,000 lb. To convert tons to lbs, multiply by 2,000; to convert back, multiply by 0.0005.
The US short ton is exactly 2,000 pounds, 907.18474 kg; the UK long ton is 2,240 pounds. Because both units are defined exactly, the factor above is exact and the results here carry no conversion error.

How accurate is the US short tons to pounds converter?
Accuracy depends on your inputs and the method's assumptions. Decimal arithmetic uses 50 significant digits, but estimates, numerical methods and source data can be less precise; the displayed rounding does not remove those limits. It is checked against 3 worked examples whose answers come from independent sources; for example, “2 ton (US) to lb” is checked against Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions).
Where does the method come from?
NIST SP 811 (2008), Guide for the Use of the International System of Units, Appendix B; NIST Handbook 44, Appendix C: General tables of units of measurement; BIPM, The International System of Units (SI Brochure), 9th edition.
