What was the base unit of temperature is SI?
The SI unit for temperature is the Kelvin.
What is th unit of measure used to express the concentration of an acid or base?
pH value(not the 'unit' just the scale)
Can water temperature get warmer than 1000 degrees Celsius?
Celsius is a scale and unit of measurement for temperature. It is named after the Swedishastronomer Anders Celsius(1701-1744), who developed a similar temperature scale two years before his death. Thedegree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperatureinterval, a difference between two temperatures or an uncertainty. The unit was known until 1948 as centigrade from the Latin "centum"translated as 100and "gradus" translated as "steps".From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere with mercury being the working material[citation needed] Although these defining correlations are commonly taught in schools today, by international agreement the unit "degree Celsius" and the Celsius scale are currently defined by two different points: absolute zero, and the triple point of VSMOW(specially prepared water). This definition also precisely relates the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature (symbol: K). Absolute zero, the hypothetical but unattainable temperature at which matter exhibits zero entropy, is defined as being precisely 0 K and −273.15 °C. The temperature value of the triple point of water is defined as being precisely 273.16 K and 0.01 °C.[1]This definition fixes the magnitude of both the degree Celsius and the kelvin as precisely 1 part in 273.16 (approximately 0.00366) of the difference between absolute zero and the triple point of water. Thus, it sets the magnitude of one degree Celsius and that of one kelvin as exactly the same. Additionally, it establishes the difference between the two scales' null points as being precisely 273.15 degrees Celsius (−273.15 °C = 0 K and 0 °C = 273.15 K).[2]
When a prefix is put in front of a base unit what does it do to the base unit?
changes how big the unit is
What is the Si base unit for energy?
There is no SI Base Unit for energy. The unit for energy, the joule is a Derived Unit.
Does temperature have a base unit?
The SI base unit for temperature is Kelvin. This is determined by the absolute zero of a substance.
The reference point for the lowest temperature on the scale for the SI unit of temperature is?
absolute zero
What is the unit of temperature on the kelvin scale?
The Kelvin, abbreviated K. The scale starts at absolute zero.
Is kelvin a unit of temperature?
yes The Kelvin scale is a way of measuring temperature from absolute zero. The gradient is the same as the Celsius (or Centigrade) scale. Not actually a unit of heat, just a measurement of temperature.
Why degree is not written with kelvin scale?
The SI unit of absolute temperature is the Kelvin, not the degree.
The kelvin scale is used to measure what?
The Kelvin scale is used to measure absolute temperature, i.e., temperature from absolute zero. The way it is defined, there are no negative temperatures on the Kelvin scale.The Kelvin scale is used to measure absolute temperature, i.e., temperature from absolute zero.

What measure temperature?
The basic unit is a Kelvin but it is common to use a degree Celsius. The Kelvin scale is absolute whereas the zero point on the Celsius scale is arbitrary.
What is the lowest scale in Celsius?
The lowest possible temperature on the Celsius scale is -273.15 °C. This is the same as 0 K on the Kelvin scale, which is the SI base unit of thermodynamic temperature. This temperature is called absolute zero, because it is the point where all molecular motion stops.
Temperatures scale used in SI?
The SI system uses the Kelvin temperature scale, which begins at 0° (at absolute zero) and uses the same degree size as the Celsius or centigrade scale. Water freezes at 273.15 °K, which is the equivalent of 0° Celsius. There are no negative temperatures on the Kelvin scale, as it is based on absolute zero and no lower temperature state can exist.
What is the unit used when measuring temperature?
There are four units for temperature: Celsius, Kelvin, Fahrenheit, and Rankine. The Kelvin scale is the same as the Celsius scale, just with the zero point being absolute zero. The Rankine scale is the same thing for the Fahrenheit scale. ■
What metric measures temperature?

Is degree celsius a si unit of measure?
The base unit for temperature is the kelvin. One degree celsius is the same as one kelvin, because kelvin starts at absolute zero, degrees celsius is kelvin plus 273.15. Celsius is used for most non-technical uses. Kelvin is just kelvin, not degrees kelvin.
