密度密度density物质的每单位体积的质量。如果物质的质量分布是均匀的，物质的体积为V，质量为m，则密度d＝m／V。在国际单位制中密度以千克／米3为单位，工程上常用吨／米3为密度单位。任何物质的体积都随温度、压力而变动，因此密度不是固定不变的，尤其是气体，通常给出标准状态(0℃、1个大气压)或常温(15～20℃)、常压下的密度，其他状态下的密度，可用气体定律推算。液体的密度和压力、温度的关系较小，而和所溶解的其他物质的浓度关系很大，因此液体不纯时，须标明溶解物的浓度，如水中的盐浓度，固体的密度和压力、温度的关系比气体和液体都小得多，但质地疏松的固体如木材、土壤，其密度和含水量关系很大，常须标明干湿程度；颗粒状和粉末状物质，如砂、水泥、粒间和粉间都有空隙，单位容积的质量称容重，不称密度。宇宙中密度最小的物质为星系间物质，其密度为2×10-31～5×10-27千克／米3，密度最大的物质为中子星，其密度估计为1014～1019千克／米3。液体和固体在一定温度与压力下的密度同纯水在标准大气压下的最大密度(温度为3.98℃时密度为999.972千克／米3)的比值称相对密度，也称比重。气体的相对密度则是其密度和标准状态下空气密度的比值。相对密度是无量纲量。也有把单位体积的重量称为比重的，因易和密度混淆，已少用。
