larger veins for a more accurate reading
The upper arm is good because for one it is accessable. You can measure it on the thigh but that requires taking your pants off. Also, take gravity and the positioning of your Aorta into account. There is a higher pressure in your thigh because all the blood is being helped down your leg by gravity. You cannot trust a wrist reading because the veins become very small and there are a lot of them, plus you once again have gravity working against you.
Because - if the arm is higher or lower than the heart - it will result in a false reading.
Assuming by 'bp' you mean blood pressure... The 'standard' tester works like this - An inflatable cuff is wrapped around the upper arm. The medic listens to the pulse in your arm as they slowly inflate the cuff with air. The amount of pressure in the cuff is displayed on a dial - and the medic notes this pressure when the pulse stops. A release valve on the cuff is slowly opened and the cuff deflates. Again - the medic listens for the pulse returning to your arm - and notes the pressure. This gives the pressure readings (for example 90/40)
Archaeologists prefer to use BP (Before Present) over BC (Before Christ) as it provides a more precise and consistent timeline. BP is based on the year 1950 as the standard reference point, which helps avoid potential religious or cultural biases associated with using BC. Additionally, radiocarbon dating, a commonly used method in archaeology, is calibrated in BP.
Resting at or just below the level of the heart. If raised higher in the air, it will affect the BP reading.
To use a blood pressure apparatus: Sit comfortably with your arm supported at heart level. Wrap the cuff around your upper arm, ensuring a snug fit. Use the pump to inflate the cuff until the pressure is above your expected blood pressure. Slowly deflate the cuff while listening to the heartbeat using a stethoscope or observing the digital display for readings.
As of July 2014, the market cap for BP p.l.c. (BP) is $157,930,682,942.25.
There are no discrete speeds for evolution. A workable method for measuring evolution could be in terms of genetic divergence, measured, for instance, in nucleotide basepairs per million per year. For humans and chimps, such a method would yield an equivalent of about 600 bp divergence per generation, ie. about 0.01 bp per million bp per year.

The symbol for BP p.l.c. in the NYSE is: BP.
Some medical conditions prevent a health professional to obtain a Blood Pressure from the arm, or the arm is simply too big. Obtaining a Blood Pressure from ones leg is an accurate reading just as on the arm, you can also get a reading from the forearm.
If you're listening with a stethoscope, you're listening to the brachial artery. In some situations, though, you may need to palpate the BP, resulting in feeling the radial artery. However, if you palpate, you can only get the systolic BP.
