silverdiv......you are talking to the crock pot expert. You really want to cook your roast on low but if you have to cook it on high depending on the size of the roast it usually should take 3-4 hours.
The symbol for cubic meters is m 3. Less formally, cubic meter is sometimes abbreviated cu m. When calculating volume, it is important to realize that volume is proportional to the cube of the linear dimension.
I have not heard any differance like standard or normal cubic meter. Cubic meter is unit measure of volume where 1 meter x 1 meter x 1 meter cube is 1 cubic meter volume. There is nothing like standard cu.meter or normal cu.meter.
