Why Convert Celsius to Romer?

The Romer scale, invented by Danish astronomer Ole Romer in 1701, was historically significant as the scale that directly influenced Daniel Fahrenheit in creating his famous scale. Understanding Romer helps explain the seemingly arbitrary reference points in Fahrenheit and provides insight into the early development of standardized temperature measurement.

How the Conversion Works

The conversion from Celsius to Romer uses the formula °Ro = (°C × 21/40) + 7.5, which equals °C × 0.525 + 7.5. Romer set the freezing point of water at 7.5° (not zero) and the boiling point at 60°. This unusual zero point influenced Fahrenheit, who later multiplied Romer's values by 4 and adjusted them.

When to Use This Converter

Use this Celsius to Romer converter when studying the history of temperature scales, understanding the origins of the Fahrenheit scale, researching early 18th-century thermometry, exploring Danish scientific history, or teaching about the development of standardized temperature measurement.
