About Converting Short tons per Cubic Meter to Long tons per Cubic yard
Short ton per Cubic Meter and Long ton per Cubic yard both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
long tons per cubic yard = short tons per cubic meter × 0.682638266057
This factor comes from each unit's defined relationship to the category's base unit: 1 short ton per cubic meter equals 907.18474 base units, and 1 long ton per cubic yard equals 1328.93918362 base units, so dividing one by the other gives the direct short ton per cubic meter-to-long ton per cubic yard factor of 0.682638266057.
Simple example
1 ton/m3 × 0.6826382661 = 0.6826382661 long ton/yd3
1 short ton per cubic meter = 0.6826382661 long tons per cubic yard.
Real-world example
1,000 ton/m3 × 0.6826382661 = 682.6382661 long ton/yd3
1,000 short tons per cubic meter = 682.6382661 long tons per cubic yard.

Frequently asked questions
How many long tons per cubic yard are in 1 short ton per cubic meter?
1 short ton per cubic meter equals 0.6826382661 long tons per cubic yard, using the exact defined conversion factor rather than an estimate.
How do I convert short ton per cubic meter to long ton per cubic yard?
Multiply the short ton per cubic meter value by 0.6826382661. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cubic yard back to short ton per cubic meter?
Use the reverse factor: 1 long ton per cubic yard equals 1.464904694 short tons per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a short ton per cubic meter?
Short ton per Cubic Meter (ton/m3) is a unit of density.
What is a long ton per cubic yard?
Long ton per Cubic yard (long ton/yd3) is a unit of density.
Is the short ton per cubic meter to long ton per cubic yard conversion exact?
Yes. Both short ton per cubic meter and long ton per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 0.6826382661 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
