Density

Converts densities between kilograms per cubic meter, grams per cubic centimeter, pounds per US gallon, and pounds per cubic foot. Pilots use it for fuel weight, and surveyors and engineers for soil and material weights. Start with the density converter. Pitfall: pounds per gallon depends on which gallon, and this converter uses the US gallon. Fuel density also changes with temperature, so use a measured value for weight and balance.
