The Système International d'Unités (SI) is progressively being adopted in all branches of science. Physiology and biophysics are no exceptions. Resistance to the use of SI-units derives from the ingrained habit of utilizing traditional units, which may appear simpler but have many limitations. The SI not only simplifies units but also involves the standardization of spelling, symbols and presentation. This article describes the relationship between the SI and the units commonly used in cardiovascular and pulmonary physiology and biophysics. It provides conversion factors for SI units in the hope that it will stimulate a wider use of these new international units.
国际单位制（SI）正在逐渐被科学的各个分支所采用。生理学和生物物理学也不例外。对使用国际单位制的抵制源于使用传统单位的根深蒂固的习惯，传统单位可能看起来更简单，但有许多局限性。国际单位制不仅简化了单位，还涉及拼写、符号和表示方法的标准化。本文描述了国际单位制与心血管和肺生理学及生物物理学中常用单位之间的关系。它提供了国际单位制的转换因子，希望能促进这些新国际单位的更广泛使用。
