1 mmHg = 0.03937 inHg
Full precision:0.03937 inHg
Step-by-Step Solution
To convert 1 mmhg to inhg, we divide by 25.4001 because one inch of mercury equals exactly 25.4001 mmhg.
1 inch of mercury = 25.4001 mmhg
Since there are 25.4001 mmhg in every inch of mercury, we divide our value by this factor:
1 ÷ 25.4001 = 0.03937 inhg
So 1 mmhg = 0.03937 inhg.
Quick check: 0.03937 × 25.4001 = 1 mmhg
Example Conversions
Example 1: 1 mmHg = 0.03937 inHg
1 ÷ 25.4001 = 0.03937
1 ÷ 25.4001 = 0.03937
Example 2: 5 mmHg = 0.19685 inHg
5 ÷ 25.4001 = 0.19685
5 ÷ 25.4001 = 0.19685
Example 3: 10 mmHg = 0.3937 inHg
10 ÷ 25.4001 = 0.3937
10 ÷ 25.4001 = 0.3937
