Whats the specific gravity for diesel?

# 2 weighs around 7 lbs.

7.65

I'm sorry I ment .765 SG


I've always used 7lbs. I'm talking #2, not 6, 8 bunker fuel for ships.



Yeah your talking about the weight of the fuel. I was talking about
specific gravity as compared to water.

Specific Gravity is dimensionless unit defined as the ratio of density
of the material to the density of water at a specified temperature.
Specific Gravity can be expressed as:

SG = = ρ / ρH2O

where

SG = specific gravity

ρ = density of fluid

ρH2O = density of water

It is common to use the density of water at 4 oC (39° F) as reference
- at this point the density of water is at the highest.

Thermal Properties of Water Density, Freezing temperature, Boiling
temperature, Latent heat of melting, Latent heat of evaporation,
Critical temperature .... .

Since Specific Weight is dimensionless it has the same value in the
metric SI system as in the imperial english system (BG).

At the reference point specific gravity has same numerically value as
density.

Example - Specific Gravity
If the density of iron is 7850 kg/m3, 7.85 grams per cubic millimeter,
7.85 kilograms per liter, or 7.85 metric tons per cubic meter - the
specific gravity of iron is:

SG = 7850 kg/m3/ 1000 kg/m3 = 7.85

where the density of water is 1000 kg/m3.

It is critical to understand the specific gravity of fluids you carry
on deck in tanks. If you do not.... and just go by volume guessing
weight you can get in mucho trouble in a heart beat.

I carried fluids that had as high as a 4.6 SG
