Neither one. Snow starts to melt at 0 c, so you'd be looking at really ugly conditions at 10 c. 40 c is a good temperature for water skiing. Minus-10 c would be a fine temperature for snow skiing; minus-40 c would be dangerous because of the risk of cold weather injury.
-20F is colder than -20C. This is because the Fahrenheit scale has a smaller degree interval than the Celsius scale, so -20F is a lower temperature than -20C.
20°C is hotter than 20°F. 20°C is equivalent to 68°F.
It is about 20F and -7C.
I think its about 20F to about 60F.
-20F to +100F
55
july is 54F january is 20F
well it depends it can range from somewhere around -20F to 90F
The ideal temperature for freezing wine to preserve its quality is around 20F (-6C).
The best commonly available ice melter by far is Calcium Chloride, works to -20F. Followed by by Magnesium Chloride, works to +5F. Then Sodium Chloride (salt), works to +20F. Calcium Chloride does not affect concrete nor damage vegetation but it can leave surfaces slippery.
It is about 20F and -7C.
The ideal temperature for freezing wine to preserve its quality and taste is around 20F (-6C). This temperature helps maintain the wine's flavor and characteristics without causing it to expand and potentially break the bottle.
