Degree celcious is used all over the world for measuring temperature
By hours and minutes.
Hours and minutes would be a sensible measure of the amount of time you spend on homework each day.
the "degree"
Any unit of time will do - day, hour, year, etc. If you want to use SI units, use seconds.
A day.
I would say "there are different temperature ranges every day".
On a cold day, you will measure a larger area compared to a hot day; metals expand when heated. So on a hot day, your steel ruler will also expand. Whatever you measure on a hot day will be relatively less compared to a cold day.
Ah, measuring a pinch of salt is like adding a touch of magic to your cooking! In the metric system, you can use a unit called a "gram" to measure a pinch of salt. Just gently sprinkle a small amount into your dish, like adding a sprinkle of happiness to brighten your day.
A thermometer is typically used to measure temperature to determine how hot the day is.
In some countries as Canada (ancient British colonies) the degree Fahrenheit is used.
Depends on the context. Inter city distances in kilometres, distances around the house or garden in metres, smaller objects in centimetres. Scientists or specialists would meause interstellar distances in light years or parsecs, accurate measures of day-to-day objects in millimetres, wavelenth of electromagnetic radiation in nanometres, etc.
Temperature is a measure of the average kinetic energy of molecules in the air. By predicting the temperature, a weatherman can estimate how much heat energy will be present in the air, giving an indication of how hot a day will feel.
