  1. STANDARD UNITS and NONSTANDARD UNITS LENGTH, MASS AND TIME

  2. The unit of quantity can be expressed with standard units and non standard units. The standard units are units which are acknowledged internationality, while nonstandard units are units which not to be valid internationality

  3. CONDITION OF STANDARD UNITS1.INTERNATIONALITY2.THE VALUE FIXED3.CAN BE MADE and REMADE WHENEVER EASLY

  4. LENGTH IS DISTANCE BETWEEN TWO POINTS A SPACEIT IS CONSIST WIDTH,HEIGHT,DISTANCE,DEEP, CIRCUMFERENCE AND DIAMETER ARE ALSOLENGTH QUANTITIES

  5. ONE STANDAR METER IS :BEFORE AGREEMENT IN USING S I : 1 METER EQUAL 1/10,000,000 DISTANCE BETWEEN NORTH POLAR UNTIL EQUATOR. IT IS EQUAL A BAR MADE OF PLATINA IRIDIUM. IT IS KEPT IN SEVRES ,PARIS, AFTER AGREEMENT IN USING S I: 1 METER IS THE SAME AS THE DISTANCE WHICH IS TRAVELED BY LIGTH IN A VACCUM IN 1/299792458 SECOND

  6. THE MEASURING DEVICE OF LENGTH QUANTITY RULE,METER TAPE,VERNIER CALIPER,AND SCREW MICROMETER

  7. THESI UNIT CAN BE ENLARGED OR LESSENED BY ADDING PERFIXES LIKE AS TABLE BELLOW

  8. Cara penulisan bil.baku (bil .berpangkat dengan dasar 10 )1. yang dapat ditulis dengan pangkat adalah angka yang merupakan kelipatan dari 10 seperti 100,10000,0,0002 2. bil baku yangmerupakan hasil kali pangkatnya + ( Positip),sedang hasilbagi pangkatnya – (negatip) 3. jika bil. Baku dikalikan pangkatnya dijumlah. 4. jika bil baku dipangkatkan pangkatnya dikalikan. 5. jika bil baku ditambah atau dikurangi maka pangkatnya harus sama.PENULISAN BILANGAN BAKU TIDAK BOLEH KURANG DARI 1 DAN LEBIH DARI 10.CONTOH ; 1200 DITULIS 1,2. 1030,00023 DITULIS 2,3 .10-4

  9. Latihan Tuliskan dengan bilangan baku1. 24000 =…………….. 9. 0.0560 =……………..2. 56km = cm 10. 8mm = dam3. 17 cm2 = µm2 11. 0,65m2 = km24. 10 m3 = mm3 12. 78 cm3 = Mm35.20 kg = mg 13. 3600 µg = g6.12500 L = kL 14. 0. 095 m3= cL7. 125 ton = mg 15. 1700 ng = kw8. 1 kg/m3 = g/cm 16. 1 m/s = km/h

  10. MASS AND WEIGHT THE MASS OF SUBSTANCE IS THE AMOUNT MATTER CONTAINED BY SUBSTANCE THE WEIGHT IS THE FORCE EXPERIENCED BY THE SUBSTANCE WHICH HAS MASS BECAUSE OF GRAVITY MASS IS DIFFERENT AS WEIGHT. THE MASS 0F SUBTANCE IS FIXED,BUT WEIGHT OF SUBSTANCE DEPENDS ON THE POSITION OBJECT ON THE EARTH AND IS AFFECTED BY THE GRAVITATIONAL FORCE . IN S I MASS USES BASIC UNIT kilogram ( kg) AND WEIGHT USES BASIC UNIT newton ( N )

  11. ONE STANDARD KILOGRAM IN S I FIXED IS TO BE EQUAL TO THE MASS OF PLATINA IRIDIUM CYLINDER. IT IS KEPT IN SEVRES ,PARIS, FRANCE

  12. THE MEASURING DEVICE OF MASS QUANTITY IS BALANCESEVERAL KIND OF BALANCE ARE:LEVER BALANCE,MARKET BALANCE,ELECTRONIK BALANCE,ARM BALANCE ( 2,3,AND 4 ARMED BALANCE )

  13. TIME • TIME IS DURATION BETWEEN TWO EVENTS. • THE S I UNIT FOR TIME IS SECOND ( S ) • ONE STANDARD SECOND BEFORE AGREEMENT IN USING S I : • 1 SECOND EQUAL1/86400 OF AVERAGE DAY IN THE EARTH’S ROTATION AFTER AGREEMENT IN USING S I: • 1 SECOND EQUAL THE TIME NEEDED BY CECIUM ATOM TO VIBRATE 9,192,770 TIMES • THE MEASURING DEVICE OF TIME QUANTITY ARE WATCH AND STOP WATCH
