• 1

  This page converts Tons of TNT to Horsepower-hours using the exact reference factor 1558.5657. That is the standard figure, so the results here match reference tables rather than rounded approximations.

• 2

  Round only the final result: keep full precision while converting Tons of TNT to Horsepower-hours and round once at the end, because rounding every intermediate step lets drift accumulate until the final figure drifts from its true value.

• 3

  With very large or very small Tons of TNT values, read the full Horsepower-hours result before copying it — scientific notation is easier to misjudge than a plain number, especially across several orders of magnitude in one conversion.

• Direction is the classic slip: Tons of TNT → Horsepower-hours multiplies by 1558.5657, never by 0.00064161557. If the horsepower-hours answer is off by roughly that factor, the ratio ran backwards — confirm the arrow and re-enter the value.

• Decimal separators corrupt input silently: a comma can be read as a thousands separator and shift a Tons of TNT value by ×1000. Control check: enter 2.5 and confirm the result equals 3896.4142 Horsepower-hours before trusting larger values.
