Example 1
Generic abbreviated form NPU03178 Pt—Plasma; kin.visc.(37 °C) = ? m2/s
Full form with a result NPU03178 Pt—Plasma; kin.visc.(37 °C) = 1.25 × 10-6 square meter per second
Abbreviated form with a result NPU03178 Pt—Plasma; kin.visc.(37 °C) = 1.25 × 10-6 m2/s
Written expression The kinetimatic viscosity of Mr. Smith’s plasma is [1.25 × 10-6m2/s. The measurement is performed at 37 °C.
