Why Convert Romer to Celsius?

Historical documents from early 18th-century Denmark and other parts of Europe may contain temperatures recorded in Romer. Additionally, understanding Romer temperatures helps explain the historical development of the Fahrenheit scale. Converting to Celsius makes these historical temperatures understandable in modern terms.

How the Conversion Works

The conversion from Romer to Celsius uses the formula °C = (°Ro - 7.5) × 40/21, which equals (°Ro × 1.9048) - 14.2857. This accounts for both the offset (Romer's 7.5° at freezing) and the different degree sizes (60° - 7.5° = 52.5° Romer between freezing and boiling, versus 100° Celsius).

When to Use This Converter

Use this Romer to Celsius converter when interpreting early 18th-century European temperature records, researching Ole Romer's scientific work, understanding historical meteorological data, studying the development of temperature scales, or converting temperatures from historical documents.
