Hi everybody,

Can anyone tell me what is the difference between calculating bunker quantity of HFO & MGO if I’m using the formula

**Mass=(Stanadard value@15 Degree Celsius) X V.C.F. X W.C.F.**

**Where v.c.f. is from ASTM 54B & w.c.f=v.c.f-0.0011**

And what about this formula

**Mass=Observed Volume X Corrected S.G.**

**WhereThe formula used to calculate the Temperature Corrected Density is:

= (Density of Fuel Oil @ 15⁰C) x [1- {(T-15) x 0.00064}]

Where:

T = temperature of oil in bunker tanks in degree Celsius,

0.00064 = Correction factor**

**Does this formula applies for both HFO & MGO??**

Thanks in advance
