Starting on a quiet Sunday morning, the fire spread quickly and overwhelmed the city’s ability to fight it alone. Fire companies from New York, Philadelphia, Wilmington, Harrisburg and elsewhere swiftly rushed in to help. They had more than enough water and people to fight the fire, but there was a problem: Most of their fire hoses wouldn’t fit the hydrants, prolonging the fire to 30 hours and damaging an area the size of 70 blocks in the city’s business district.</p></div> </div> <div class="nist-card__links"> <div class="nist-card__button"> <a href="/web/20230928042152/https://www.nist.gov/feature-stories/why-you-need-standards" class="usa-button ">Read more about why you need standards</a> </div> </div> </div> </div> </div> </div> <div class="nist-content-row nist-content-row--width-full paragraph paragraph--type--text-bg-color paragraph--view-mode--default"> <div class="nist-content-row__inner"> <div class="text-long"> <div class="grid-container padding-top-5"> <div class="nist-region-heading"> <h2>How Do You Measure It?</h2> </div> <p class="width-desktop">Much of the world around us would be a mystery without good measurements.
