About Converting Long tons per Imperial gallon to Nanograms per Cubic yard
Long ton per Imperial gallon and Nanogram 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
nanograms per cubic yard = long tons per imperial gallon × 1.708773e+17
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per imperial gallon equals 223499.074765 base units, and 1 nanogram per cubic yard equals 1.307951e-12 base units, so dividing one by the other gives the direct long ton per imperial gallon-to-nanogram per cubic yard factor of 1.708773e+17.
Simple example
1 long ton/imp gal × 1.708773e+17 = 1.708773e+17 ng/yd3
1 long ton per imperial gallon = 1.708773e+17 nanograms per cubic yard.
Real-world example
1,000 long ton/imp gal × 1.708773e+17 = 1.708773e+20 ng/yd3
1,000 long tons per imperial gallon = 1.708773e+20 nanograms per cubic yard.

Frequently asked questions
How many nanograms per cubic yard are in 1 long ton per imperial gallon?
1 long ton per imperial gallon equals 1.708773e+17 nanograms per cubic yard, using the exact defined conversion factor rather than an estimate.
How do I convert long ton per imperial gallon to nanogram per cubic yard?
Multiply the long ton per imperial gallon value by 1.708773e+17. The converter above does this instantly to whatever precision you set.
How do I convert nanogram per cubic yard back to long ton per imperial gallon?
Use the reverse factor: 1 nanogram per cubic yard equals 5.852152e-18 long tons per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per imperial gallon?
Long ton per Imperial gallon (long ton/imp gal) is a unit of density.
What is a nanogram per cubic yard?
Nanogram per Cubic yard (ng/yd3) is a unit of density.
Is the long ton per imperial gallon to nanogram per cubic yard conversion exact?
Yes. Both long ton per imperial gallon and nanogram per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 1.708773e+17 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.
