    What is the formula for converting atm to Torr?
    example: 1.87 atm to Torr

    Also what is the formula for converting Torr to mmhg?
    example: 748 Torr to mmHg

    What about mb to kPa?
    example: 998mb to pKa

    Then in. Hg to atm
    example:26,88 in Hg to atm

    what is the formula for converting atm to Torr?
    example: 1.87 atm to Torr
    1 atm = 760 Torr,
    So 1.87 atm = 1.87 * 760 Torr = 1421.2 Torr

    Also what is the formula for converting Torr to mmhg?
    example: 748 Torr to mmHg
    Torr and mmHg are the same unit. So 1 Torr = 1 mmHg.
    748 Torr = 748 mmHg.

    What about mb to kPa?
    example: 998mb to kPa
    1 bar = 100,000 Pa
    1 mb (millibar) = 0.001 bar = 100 Pa = 0.1 kPa
    So 998 mb = 998 × 0.1 kPa = 99.8 kPa

    then in. Hg to atm
    example:26,88 in Hg to atm

    1 inch = 25.4 mm, so 1 in Hg = 25.4 mmHg.
    We also know that 1mmHg = 1.3158×10−3 atm
    Therefore, 1 in Hg = 25.4 ×1.3158×10−3 = 3.342 ×10−2 atm.
    Then 26.88 in Hg = 26.88 × 3.342 ×10−2 = 0.898 atm.

    See the attached table for pressure units conversion.

    Example reading: 1 Pa = 1 N/m² = 10−5 bar = 10.197×10−6 at = 9.8692×10−6 atm ....etc.
