The difference, or subtraction, between120 hertz and 240 hertz is 120 hertz. These two frequencies are typically used to measure the refresh rate of high-definition televisions. Although in theory a higher refresh rate frequency is better, in actuality it makes little difference, explains PC Magazine.Know More
Generally, the frequency of a refresh rate refers to how many frames per second are displayed. One advantage of a high refresh rate is that it reduces the choppiness of fast lateral movement in the source image, found in many kinds of sports broadcasts.
Most source footage has a frame frequency of 24 to 60 hertz. To compensate for the difference between this source frequency and refresh rate on a display, many high-definition television interpolate created frames into the source footage.Learn more in Measurements
The abbreviation "kph" means the number of kilometers traveled in an hour, whereas "mph" is the number of miles traveled in an hour. Convert mph to kph by taking the mph and multiply it by 1.61. The inverse formula is to take the kph and multiply the figure by 0.61. In other words, 1 mile is 1.61 kilometers, and 1 kilometer is 0.61 miles.Full Answer >
PSI and PSIG are both units of measurement for describing the amount pressure a gas or fluid is exerting. However, PSIG specifies what the measurement is relative to, whereas PSI does not. In both units, the letters "psi" are an abbreviation for "pounds per square inch."Full Answer >
The difference between mg and mcg is in terms of value, with 1 mg being equivalent to 1000 mcg. These abbreviations stand for milligram and microgram respectively.Full Answer >
The difference between compression and tension is that a compressing force causes an object to shorten in the direction of the force, while a tension force causes an object to lengthen in the direction of the force. Regardless of the strength of the material, compression and tension forces always cause some amount of deformation. Different materials deform in different amounts and return to their previous shape differently as well.Full Answer >
