About Converting Grams per Cubic Meter to Long tons per Cubic Meter
Gram per Cubic Meter and Long ton per Cubic Meter 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 meter = grams per cubic meter × 9.842065e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic meter equals 0.001 base units, and 1 long ton per cubic meter equals 1016.0469088 base units, so dividing one by the other gives the direct gram per cubic meter-to-long ton per cubic meter factor of 9.842065e-7.
Simple example
1 g/m3 × 9.842065e-7 = 9.842065e-7 long ton/m3
1 gram per cubic meter = 9.842065e-7 long tons per cubic meter.
Real-world example
1,000 g/m3 × 9.842065e-7 = 0.0009842065 long ton/m3
1,000 grams per cubic meter = 0.0009842065 long tons per cubic meter.

Frequently asked questions
How many long tons per cubic meter are in 1 gram per cubic meter?
1 gram per cubic meter equals 9.842065e-7 long tons per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic meter to long ton per cubic meter?
Multiply the gram per cubic meter value by 9.842065e-7. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cubic meter back to gram per cubic meter?
Use the reverse factor: 1 long ton per cubic meter equals 1,016,046.909 grams per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per cubic meter?
Gram per Cubic Meter (g/m3) is a unit of density.
What is a long ton per cubic meter?
Long ton per Cubic Meter (long ton/m3) is a unit of density.
Is the gram per cubic meter to long ton per cubic meter conversion exact?
Yes. Both gram per cubic meter and long ton per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 9.842065e-7 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.
