Counts per minute dose reading. This modifies the tube characteristic so each count resulting from a particular radiation type is equivalent to a specific quantity of deposited dose. More can be found on radiation dose and dose rate at absorbed dose and equivalent dose. Disintegrations per minute (dpm) and disintegrations per second (dps) are measures of the activity of the source of radioactivity. The SI unit of radioactivity, the becquerel (Bq), is equivalent to one disintegration per second. This unit should not be confused with cps, which is the number of counts received by an instrument from the source. One dps (one dpm)
Cup (unit) respectively, the difference being the volume lost to evaporation during brewing. Australia, Canada, New Zealand, and some other members of the Commonwealth of Nations—being former British colonies that have since metricated—employ a "metric cup" of 250millilitres. Although derived from the metric system, it is not an SI unit. A "coffee cup" is 1.5 dL or 150 millilitres or 5.07 US customary fluid ounces, and is occasionally used in recipes. It is also used in the US to specify coffeemaker sizes (what can be referred to as a "Tasse à café"). A "12-cup" US coffeemaker makes 57.6 US customary fluid ounces
