In computer science and numerical analysis, unit in the last place or unit of least precision (ulp) is the spacing between two consecutive floating-point numbers, i.e., the value the least significant digit (rightmost digit) represents if it is 1. It is used as a measure of accuracy in numeric calculations. [1]

Typical airflow in a four-stroke engine: In stroke #1, the pistons suck in (aspirate) air to the combustion chamber through the opened inlet valve.. A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a ...
The mean British thermal unit (BTU) is 1/180 of the heat required to raise the temperature of one pound (450 g) of water from 32 to 212 °F (0 to 100 °C) at a constant atmospheric pressure. It is about equal to the quantity of heat required to raise one pound of water 1°F (5 ⁄ 9 °C). Busbar
