Convert celsius to newton in 3 clicks.

Ever wondered how scientists measured temperature before modern scales took over? Let's explore one of history's forgotten gems, the Newton temperature scale. While you'll never see it on your weather app, this 18th century invention reveals fascinating insights about early thermometry. Our converter bridges past and present, letting you instantly translate today's Celsius readings into Isaac Newton's original temperature units.

Unit definitions

What is a celsius (°c)?

• Description: The standard temperature scale used worldwide (except in the USA)
• Symbol: °C
• Common uses: Weather reports, cooking, scientific research
• Definition: Sets water's freezing point at 0°C and boiling point at 100°C at sea level

What is a newton (°n)?

• Description: Obsolete temperature scale created by Isaac Newton
• Symbol: °N
• Common uses: Historical scientific documents
• Definition: Based on linseed oil's expansion, with 0°N as melting snow and 33°N as boiling water

Conversion formula

Newton = Celsius × (11/100) or °N = °C × 0.33

Example calculations

1. Room temperature (20°C to Newton):
   20 × 0.33 = 6.6°N
   (That's slightly warmer than Newton's "moderate air" reference point)
2. Freezing point conversion:
   0°C × 0.33 = 0°N
   (Scales align at water's freezing temperature)

Historical background

Isaac Newton dabbled in temperature measurement between his physics breakthroughs. In 1701, he published his "Scala Graduum Caloris" using linseed oil's expansion in glass tubes. His scale had 12 reference points from "air in winter when water begins to freeze" (0°N) to "glowing coals" (192°N). The modern simplified version with water's boiling at 33°N emerged later through standardization efforts. Though Newton himself never actually used that exact value, if we're being picky about historical accuracy.

Fun fact: Newton's original thermometer contained a linseed oil blend that sometimes froze in cold English winters, making early measurements... let's say "challenging."

Interesting facts?

1. Newton's scale predates Celsius by 41 years. Anders Celsius introduced his scale in 1742
2. The 33:100 ratio between scales comes from Newton's observation of liquid expansion rates
3. Some 18th-century brewers preferred the Newton scale for monitoring fermentation
4. Modern recreations show Newton's original thermometer had ±2°N accuracy
5. The scale was briefly called "Newton's degrees of heat' before standardization
