Density Calculator – CELCIUS
Description
Converts density readings taken with a hydrometer to corrected density at 15°C
Separate scales for 3 different types of fuel:
- Kerosene (Jet A, Jet A-1, JP 5, JP 8)
- Wide Cut (JP 4, Jet B)
- Avgas
Scales read in kg/m³
Instructions
- Rotate the disk until the observed hydrometer reading is aligned with observed temperature.
- Read the corrected density at the 15°C arrow.
NOTE: Results obtained with this calculator in the density range from 770 to 784 kg/m³ (or a correction that goes through this range) cannot be compared to the printed tables because we have avoided error created by this transition zone (see Volume X of Petroleum Measurement Tables (D1250-80/IP200), pages X-73 to X-79). For jet fuels, we extended the curve upward using the original equation without entering the transition zone. For avgas, we extended the gasoline curve downward in the same manner. From a technical standpoint, our scales will yield more accurate results than the printed tables.
