Note however, that specific disciplines such as oceanography, as well as educational exercises, do use the "ppt" abbreviation. "One part per thousand" denotes one part per 1,000 (10 3) parts, and a value of 10 −3. This is equivalent to about ninety seconds out of one day. One part per ten thousand is denoted by the permyriad sign (‱).
Bangladesh, with a population of 144 million and a GDP of $275.5 billion therefore has a GDP per capita of approximately $2,000. Its annual energy consumption was only 0.61 quad (0.64 EJ), making its Energy Intensity a mere 2,003 BTU (2,113 kJ) per dollar—a quarter of the US rate. Low standards of living and economic performance primarily ...

Two very similar expressions for δ 15 N are in wide use in hydrology. [2] Both have the form 1000 ⋅ s − a a {\displaystyle 1000\cdot {\frac {s-a}{a}}} ‰ (‰ = permil or parts per thousand) where s and a are the relative abundances of 15 N in respectively the sample and the atmosphere.

An important driver of energy consumption of cars per passenger is the occupancy rate of the vehicle. Although the consumption per unit distance per vehicle increases with increasing number of passengers, this increase is slight compared to the reduction in consumption per unit distance per passenger.
