Convert 8.1cps to mm2/s using a density of 1017.72

First you need to know the density of that particular rock. Then, find its volume by:

Volume = Mass (400tons) / Density

After that, multiply by the Bulk Factor.
Bulk factor of 1.6 means that when you dig 1 cubic metre of rock
it bulks to 1.6 cubic metres in the lorries.

Google calculator gives 1US ton = 907.185 kg
If your ton is US ton, then 400ton = 400*0.907185 or 362.874 kg
-----------------------------
Example: Sandstone (porous): Density = 2.5 kg/m3
(ref. https://www.nrc.gov/docs/ML0807/ML080700314.pdf)

Uncut 400 us tons of this Sandstone then has a volume of 362.874kg / 2.5kg/m3, giving 145.15 m3

Now get your cut volume by multiplying by the bulk factor.
This gives: 145.15 m3 x 1.6 = 232.24 m3

Hope this is what you wanted.

This looks like part of a homework question. What is the unit f/mm2? Farads per square millimeter? What is the unit that goes with the numbers? Is it Farads? In that case, you would need to know the area to calculate the capacitance per unit area.

Divide one by the other and get 3.196924428822496.
Divide 489.89 by that and get 153.1127841455705

Converting MG to ML will vary depending upon the density. It is not possible to know how many MG equal ML because milligrams are used to measure weight and milliliters are used to measure volume. You would need to know the density of the item that is being measured...

Milligram is a unit of mass (or weight), milliliter is a unit of volume. Any conversion between them depends on the density.

62.5 milligrams of water occupies 62.5 milliliters. 62.5 milligrams of gold occupies about 3.2 milliliters.

1 m2 = 1.000.000 mm2 because 1 m = 1.000 mm.

If you feel helped RATE please !

1 P[oise] = 1 g / ( cm * s ) is a unit used for dynamic viscosity.
1 St[okes] = 1 m² / s is used for kinematic viscosity.

To get the kinematic viscosity from dynamic viscosity, you need to divide the latter by the density of the liquid in question. You did not provide this value, so I cannot do the calculation for you, but you should be able to do your homework with this hint yourself. All you need to take care of is to adjust the scale factors later. 100 cP = 1 P, 1000000 mm² / s = 1 m² / s = 1 St.

Thank you for this info. I used your advice to fix my HP printer and it worked. By the way, great link to HP support parges on the www.partshere.com site. I was able to fix my printer and by the way purchased more printer parts and fusers. Thank you again!
