Measurement: pressure
| First object | Value |
|---|---|
| 1 hPa | 100 Pa |
| 1 GPa | 1,000,000,000 Pa |
100 ÷ 1,000,000,000 ≈ 1.00e-7
Sources & method
One pascal is one newton per square metre. Prefixes change the scale only; this comparison does not convert between gauge and absolute pressure.
Ratio = first value ÷ second value. For areas, side lengths use the square root of the area ratio. Diameter and height use a linear scale.
