The 1976 standard atmosphere calculator computes atmospheric properties like density, temperature, pressure and speed of sound up to 86 kilometers altitude. This tool is mainly used by aeronautical engineers to perform calculations for aircraft. But if you always wanted to know the standard air temperature at 30,000 feet, go ahead and give it a try.
The Digital Dutch unit converter converts angle, area, bits & bytes, density, electric current, energy, force, fuel consumption, length, mass, power, pressure, speed, temperature, time and volume units.
A long long time ago, before Flickr, Instagram or Facebook existed, Arles Image Web Page Creator was a really popular way to publish photo galleries from a Windows PC on your own website. It is not supported anymore, but more than two decades after its creation, some die-hards 🤠 still use it.
