What is difference between hardness and toughness?
Toughness is the ability of steel to absorb energy. Hardness is the ability of steels to withstand wear. Hardness is the ability of material to withstand the indent and is measured in rockwel or vickers. also it is a measure of stiffness of material. but hardenability is ability of material to become hardened by various methods of hardening such as carburising or quenching. it is firmly dependent on quantity of carbon in that material. and actually it doesn't have any measuring unit !

What is 8.5 sones in db?
You can convert the loudness in sones to the loudness level in phons. 8.5 sones equals 70.9 phons. The convertion from sone to dB is only a guess. Scroll down to related links and read "Correlation between sones und phons".
What is the correlation between the BTU of an air conditioner and the size of the area you wish to cool?
It depends on how many people and how many windows are in the home. As a rough rule of thumb, every 500sq ft needs 1 ton. In lower humidity areas, that can be dropped back some. There is no correlation. The cooling capacity of the ac unit (btu) should be matched to the heat gain or load of the space to be cooled. Not by rules of thumb estimating load by size. Two spaces of equal size can certainly have differing loads, thus requiring different tonnage.
What unit of measure will you use to measure how long between blinking of your eyes?
I would use the unit of time, such as seconds or milliseconds, to measure the duration between blinks of the eyes.
What is the correlation between tablet hardness unit SCU and Kp?
1 kp=1.4 S.C.U. (Strong-Cobb Units)
What is tablet hardness and friability?
what is the tblet hardness,what is its unit ,we aply hydraulic pressure on tablet compression mchine but in result we gain hardness on tablet,how the pressure is converted into hardness unit. Friability refers to the ability of the compressed tablet to avoid fracture and breaking apart during transport.
Hydraulic pressure on tablet compression machine but in result gain hardness on tablet how the pressure is converted into hardness unit?
In the tablet compression machine main principle is compressing the upper & lower puch in a die hole . the hydraulic pressure plays a key role if we increase the hydra. pressue more compressing force on tablet then it becomes more hard.
What is correlation coefficient of correlation?
correlation measure the strength of association between to variables.but some times both variables are not in same units.so we cannot measure it with the help of correlation. in this case we use its coefficent which mean unit free. that,s why we use it.
Is shore a unit of hardness for teflon?
No, "shore" is not a unit of hardness used for Teflon. Teflon's hardness is typically measured using the Rockwell or Vickers hardness scale. Shore hardness is more commonly used to measure the hardness of rubber and soft materials.
What is the unit of hardness?
The unit of hardness is typically expressed in terms of Rockwell (HRC), Vickers (HV), or Brinell (HB) scale depending on the specific test method used. Hardness is a measure of a material's resistance to deformation or indentation.
What is the unit for brinell hardness number?
The unit of Brinell Hardness Number is same as that for stress.
Distinguish between correlation and regression?
Correlation is a measure of the degree of agreement in the changes (variances) in two or more variables. In the case of two variables, if one of them increases by the same amount for a unit increase in the other, then the correlation coefficient is +1. If one of them decreases by the same amount for a unit increase in the other, then the correlation coefficient is -1. Lesser agreement results in an intermediate value. Regression involves estimating or quantifying this relationship. It is very important to remember that correlation and regression measure only the linear relationship between variables. A symmetrical relationshup, for example, y = x2 between values of x with equal magnitudes (-a < x < a), has a correlation coefficient of 0, and the regression line will be a horizontal line. Also, a relationship found using correlation or regression need not be causal.
What is the correlation coefficient of -0.80 is found between factor A and factor B?
The correlation coefficient is a statistical measure of the extent to which two variables change. A correlation coefficient of -0.80 indicated that, on average, an increase of 1 unit in variable X is accompanied by a decrease of 0.8 units in variable Y. Note that correlation does not imply causation.
Is it possible for the correlation and the slope to have opposite signs?
No, it is not possible for the correlation and the slope to have opposite signs in a linear regression context. The correlation coefficient indicates the direction and strength of a linear relationship between two variables, while the slope represents the change in the dependent variable for a unit change in the independent variable. If the correlation is positive, the slope will also be positive; if the correlation is negative, the slope will likewise be negative.
Is there any fundamental unit associated with Rockwell Hardness Test?
No, because hardness is not a fundamental quality
What hand held unit has windows?
the new windows tablet.
