Shoe size technical specification from International Standards Organisation. It contains three conversion tables (for adults and children) which feature major shoe sizing systems (e.g., Mondopoint, United States, European, United Kingdom, China, and Japan). Each table is based on actual foot length measurement (insole) in millimeters; typical last length ranges are also included. The standard includes conversion tables for Mondopoint (USSR/Russian/Chinese/Japanese/Korean systems) using length steps of 5 mm and 7.5 mm, European Paris point system, and UK 1/3 inch system. The standard has also been adopted as Russian GOST R 57425-2017. The standard is maintained by ISO/TC 137, which also developed ISO/TS 19408:2015
Zero Point Frontiers Corporation Launch Vehicle Initial Sizing tool (eLVis) is a tool for estimating launch vehicle for desired mission. It shares the performance prediction engine with Instarocket, and allows for large numbers of data value sweeps to find optimum propellant splits between the various stages of the vehicle. Users can quickly set up new concepts and compare them to multiple concepts and existing vehicles. Zero Point Frontiers Corporation Zero Point Frontiers Corporation (ZPFC) is a private aerospace firm based in Huntsville, Alabama. They, along with several other companies such as SpaceX, Blue Origin and Firefly Space Systems are proponents of NewSpace: a movement
