For example, in the 1930s Widmark measured alcohol and blood by mass, and thus reported his concentrations in units of g/kg or mg/g, weight alcohol per weight blood. Blood is denser than water and 1 mL of blood has a mass of approximately 1.055 grams, thus a mass-volume BAC of 1 g/L corresponds to a mass-mass BAC of 0.948 mg/g.
The Swedish Transport Agency trialed it in 1999 and offered a programme of alcohol interlock device with medical certificates for drivers convicted with a BAC level between 0.2 and 0.9 g/l and a 2 year programme for convicted repeat offenders (within a five-year period), and offenders with a BAC level of at least 1.0 g/. As of 2020, about 3,000 ...
I could see how someone might get the impression that .08 grams per deciliter of blood was the same volume as .08 mg/L of breath, so I changed the values to reflect the same volume for each unit of measure mentioned. (i.e., 0.10 g/dL of blood alcohol is the same BAC as 0.476 mg/L of breath alcohol and the same as 0.10 g/210L of breath alcohol).
Diego Godinez had a blood-alcohol content of 0.21% — far in excess of the legal limit of 0.08% — when arrested after the crash last month that killed the girl and left an 11-year-old boy ...
Gay is one of four players — along with Carmelo Anthony, LeBron James and Chris Paul — to average 10 or more points between 2006-07 and 2020-21.
In countries without labeling, it is possible to calculate the pure alcohol mass in a serving from the concentration, density of alcohol, and volume: = For example, a 350 ml (12 US fl oz) glass of beer with an ABV of 5.5% contains 19.25 ml of pure alcohol, which has a density of 0.78945 g/mL (at 20 °C), [ 32 ] and therefore a mass of 15.20 ...
Three recent high school graduates were killed and another was seriously injured when a speeding Tesla Cybertruck crashed and burst into flames in California.
The forerunner of the breathalyzer was first demonstrated by Professor Rolla H. Harger of Indiana University, who showed how breath contained in a balloon could be dispersed into sulfuric acid and then accurately measured to calculate blood alcohol content. [21] Harger would patent the "Drunkometer" in 1938 for use by police. [22]
