Kelvin

Definition

Kelvin (symbol: K) is the base unit of temperature in the International System of Units (SI). The Kelvin scale is an absolute temperature scale starting from absolute zero, the point at which molecular motion ceases.

History/Origin

The Kelvin scale was developed by Scottish engineer and physicist William Thomson, 1st Baron Kelvin, in the mid-19th century. It was designed to provide an absolute reference point for temperature measurements. The Kelvin scale is based on the properties of gases, and absolute zero was conceptualized as the point where the volume of gas would theoretically be zero.

Current Use

Kelvin is primarily used in scientific contexts, particularly in physics and chemistry, where precise temperature measurements are required. It is also used in fields such as astronomy, cryogenics, and engineering. Kelvin is essential for scientific research, where understanding temperature at an absolute scale is crucial.

Rankine

Definition

Rankine (symbol: °R) is a unit of temperature in the Imperial system. The Rankine scale is an absolute temperature scale, similar to the Kelvin scale, but using Fahrenheit degrees.

History/Origin

The Rankine scale was developed by Scottish engineer and physicist William John Macquorn Rankine in 1859. It was designed to provide an absolute reference point for temperature measurements in Fahrenheit degrees, where absolute zero is 0°R.

Current Use

Rankine is primarily used in engineering fields, particularly in thermodynamics and aerospace engineering. It is also used in some scientific contexts where temperature measurements need to be expressed in Fahrenheit-based absolute values.

Step-by-Step Conversion Instructions

Example: Convert 300 K to Rankine

  1. Convert Kelvin to Rankine:

    • Use the formula: ( \text{°R} = \text{K} \times \frac{9}{5} )

    • Calculation: ( 300 \times \frac{9}{5} = 540 )°R

Practical Examples

  1. Example 1: If the temperature is 320 K, convert it to Rankine using the formula (320 (\times) (\frac{9}{5}) = 576°R).

  2. Example 2: For a temperature of 290 K, convert to Rankine using the formula (290 (\times) (\frac{9}{5}) = 522°R).

Inches to cm to Feet Conversion

Definition

Inches, centimeters, and feet are units of length used in different measurement systems. An inch (symbol: in) is a unit in the Imperial and US customary systems, a centimeter (symbol: cm) is part of the metric system, and a foot (symbol: ft) is also a unit in the Imperial and US customary systems.

Conversion Formula and Factor

  • Inches to centimeters: ( \text{cm} = \text{inches} \times 2.54 )

  • Centimeters to feet: ( \text{feet} = \frac{\text{cm}}{30.48} )

Step-by-Step Conversion Instructions

Example: Convert 20 inches to feet

  1. Convert Inches to Centimeters:


  • Use the formula: ( \text{cm} = \text{inches} \times 2.54 )

  • Calculation: ( 20 \times 2.54 = 50.8 ) cm


  1. Convert Centimeters to Feet:


  • Use the formula: ( \text{feet} = \frac{50.8}{30.48} )

  • Calculation: ( \frac{50.8}{30.48} \approx 1.67 ) feet

Practical Examples

  1. Example 1: If you have a length of 15 inches, first convert it to centimeters (15 inches (\times) 2.54 = 38.1 cm), then convert to feet (38.1 cm / 30.48 ≈ 1.25 feet).

  2. Example 2: For a 35-inch measurement, convert to centimeters (35 inches (\times) 2.54 = 88.9 cm), then convert to feet (88.9 cm / 30.48 ≈ 2.92 feet)..
