WHO
Daniel Gabriel Fahrenheit Anders Celsius Lord Kelvin
WHEN 1724 1743 1848
HOW/WHY Used a brine = 0° Used Freezing water = 0° Since there are no negatives in
Used body temp = 100° Used Boiling water = 100° thermal energy, he started the
scale at zero.
Temperature:
Boiling Water 212 100 373
Body Temp 98 37 310
Room Temp 77 25 298
Freezing water 32 0 273
Liquid Nitrogen -346 -196 63
Absolute Zero -459 -273 0
Conversions:
Fahrenheit F = C*9/5 + 32 F = K*9/5 + 32
Celsius C = F-32*5/9 C = K – 273
Kelvin K = F+459*5/9 K = C + 273
