  2. Degree of frost - Wikipedia

    en.wikipedia.org/wiki/Degree_of_frost

    "Degree" in this case can refer to degree Celsius or degree Fahrenheit. When based on Celsius, 0 degrees of frost is the same as 0 °C, and any other value is simply the negative of the Celsius temperature. When based on Fahrenheit, 0 degrees of frost is equal to 32 °F. Conversion formulas: T [degrees of frost] = 32 °F − T [°F]

  3. Frost resistance - Wikipedia

    en.wikipedia.org/wiki/Frost_resistance

    Frost resistance is the ability of plants to survive cold temperatures. Generally, land plants of the northern hemisphere have higher frost resistance than those of the southern hemisphere . [ 1 ]

    Energy required to move a unit charge through an electric field from a reference point volt (V = J/C) L 2 M T −3 I −1: extensive, scalar Electrical resistance: R: Electric potential per unit electric current ohm (Ω = V/A) L 2 M T −3 I −2: extensive, scalar, assumes linearity Electrical resistivity: ρ e: Bulk property equivalent of ...

  5. Tog (unit) - Wikipedia

    en.wikipedia.org/wiki/Tog_(unit)

    So that practical clothing may be described conveniently by a range of small integers, the unit of thermal resistance, to be called the “tog”, is the resistance that will maintain a temperature difference of 0.1°C. with a flux of 1 watt per square metre, or in more practical terms, 10°C. with a flux of 1 watt per square decimetre.

  6. Freezing air temperature - Wikipedia

    en.wikipedia.org/wiki/Freezing_air_temperature

    Freezing [1] or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface. This is usually measured at the height of 1.2 metres above the ground surface.

  7. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    These are physical quantities with dimension homogeneous to pressure and force per unit surface. The traditional measure unit for strength are therefore MPa in the International System of Units, and the psi between the United States customary units. Strength parameters include: yield strength, tensile strength, fatigue strength, crack ...

  8. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    Converting units of temperature differences (also referred to as temperature deltas) is not the same as converting absolute temperature values, and different formulae must be used. To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT} °F = ⁠ 9 / 5 ⁠ {ΔT} °C.
