Celsius Is Hotter Than You Imagine—Here’s the Shocking Number When we talk about temperature in Celsius, most people associate 0°C with freezing and 100°C with boiling water—simple, right? But what if we told you that Celsius’s upper limits are far hotter than you’d expect? Get ready: temperatures well above 150°C are not only real—they’re part of everyday life and science. Here’s the jaw-dropping number: the boiling point of water at standard pressure is 100°C (212°F), but under extreme industrial conditions, cylinder pressures can push localized Celsius levels to over 300°C. That’s 150°C hotter than most realize. ### Why Do Celsius Measurements Surprise So Many? Celsius is commonly taught in school as a 0–100 scale, but it’s used far beyond water’s melting and boiling points. In high-heat industrial processes—like metal fabrication, chemical synthesis, or thermal testing—Celsius readings can soar dramatically. When pressurized systems elevate vapor pressure, tiny far higher than standard atmospheric boiling points, Celsius spikes emerge.
