Table 2.3 Metric System and Equivalents

The following metric system equivalents and approximate conversion factors help meet the requirements of Public Law 100-418. This law requires each Federal agency to use the metric system of measurement by Fiscal Year 1992 in procurements, grants, and other business related activities.

 

Linear Measure Liquid Measure
1 centimeter = 10 millimeters = 0.39 inch 1 centiliter = 10 milliliters = 0.34 fl. ounce
1 decimeter = 10 centimeters = 3.94 inches 1 deciliter = 10 centiliters = 3.38 fl. ounces
1 meter = 10 decimeters = 39.37 inches 1 liter = 10 deciliters = 33.82 fl. ounces
1 decameter = 10 meters = 32.8 feet 1 decaliter = 10 liters = 2.64 gallons
1 hectometer = 10 decameters = 328.08 feet 1 hectoliter = 10 decaliters = 26.42 gallons
1 kilometer = 10 hectometers = 3,280.8 feet kiloliter = 10 hectoliters = 264.18 gallons


 

Weights Area Measure
1 centigram = 10 milligrams = 0.15 grain 1 sq. centimeter = 100 sq. millimeters = 0.155 sq. inch
1 decigram = 10 centigrams = 1.54 grains 1 sq. decimeter = 100 sq. centimeters = 15.5 sq.inches
1 gram = 10 decigrams = 0.035 ounce 1 sq. meter (centare) = 100 sq. decimeters = 10.76 sq. feet
1 decagram = 10 grams = 0.35 ounce 1 sq. decameter (are) = 100 sq. meters = 1,076.4 sq. feet
1 hectogram = 10 decagrams = 3.52 ounces 1 sq. hectometer (hectare) = 100 sq. decameters = 2.47 acres
1 kilogram = 10 hectograms = 2.2 pounds 1 sq. kilometer = 100 sq. hectometers = 0.386 sq. mile
1 quintal = 100 kilograms = 220.46 pounds  
1 metric ton = 10 quintals = 1.1 short tons  

 

Cubic Measure

1 cu. centimeter = 1000 cu. millimeters = 0.06 cu. inches
1 cu. decimeter = 1000 cu. centimeters = 61.02 cu. inches
1 cu. meter = 1000 cu. decimeters = 35.31 cu. feet

ETC Bulletin 25-001: Retrofitted Hot/Cold Beverage Kits - 2025 Field Season

Date: April 16, 2025
Questions?  Please contact:
Equipment Technology Committee

Due to spout failures and the associated risk of burn injuries, manufacturers have retrofitted the Hot/Cold Beverage Kits using a heat-shrinking band to secure the black spout at the insertion site. The updated kits feature a fluorescent label on each full kit assembly for easy identification. Catering units are encouraged to confirm the clear heat-shrinking bands are intact around each spout before filling.

ETC Bulletin 24-001 regarding Hot/Cold Beverage Kits has been archived and replaced by ETC Bulletin 25-001 for the 2025 season.

RMC Memo 25-01: Summary of Updates to Safety Officer Positions

Date: April 9, 2025
Questions?  Please contact:
RMC Member Eric Fransted

The Risk Management Committee (RMC) serves as the position steward for all Safety Officer incident positions and continues to improve position standards, training, and naming conventions. The implementation of Complex Incident Management (CIM) required changes to position titles. RMC collaborated with the NWCG Incident Position Standards Committee (IPSC) to propose and implement these updates.
