WebNov 17, 2024 · In the United States, horizontal and vertical illuminances are measured in footcandles; most other countries measure this luminous emittance in lux. Footcandles and lux are quite similar; one lux equals one lumen per square meter. If you have a lux light intensity measurement, simply divide it by 10.76 to solve for footcandles.

WebThe klett-Sumerson colorimeter scale is graduated in units proportional to Optical Density (OD). The actual numerical values represent the OD divided by two, with the decimal point omitted. For eg., a scale of 250 corresponds to OD of 0.500. The formula relating scale reading and OD (Optical Density) is: D = R X 2/1000 where D is density and R ...
