When we are in the design process of high temperature insulation of calcium silicate board and other materials, we often find that different manufacturers and different standards often exist in a variety of different units, some use the imperial system, some use the standard unit system, so how quickly between the various units to convert it? In order to facilitate the use of designers, we for high-temperature insulation design of common imperial and standard units for the summary, the production of this conversion table, I hope to help you designers better design work.
